This case related to the issue #41522.
```
Zone.root
.fork({
name: 'xhr',
onHasTask(delegate, currentZone, zone, taskState) {
console.log('hasMacrotask', taskState.macroTask);
return delegate.hasTask(zone, taskState);
},
})
.run(() => {
const xhr = new XMLHttpRequest();
xhr.open('GET', 'https://cdnjs.cloudflare.com/ajax/libs/zone.js/0.11.4/zone.min.js');
xhr.addEventListener('load', () => {
throw new Error();
});
xhr.send();
});
```
zone.js invoke all `onload` event handlers before change the XHR task's state from
`scheduled` to `notscheduled`, so if any `onload` listener throw error, the XHR task
wlll be hang to `scheduled`, and leave the macroTask status in the zone wrongly.
This has been fixed in the previous commit, this commit add test to verify the case.

`zone.js` patches event listeners and run all event listeners together, if
one event handler throws error, the listeners afterward may not be invoked.
Reproduction:
```
export class AppComponent implements AfterViewInit {
@ViewChild('btn') btn: ElementRef;
title = 'event-error';
constructor(private ngZone: NgZone) {}
ngAfterViewInit() {
this.ngZone.runOutsideAngular(() => {
this.btn.nativeElement.addEventListener('click', () => {
throw new Error('test1');
});
this.btn.nativeElement.addEventListener('click', () => {
console.log('add eventlistener click');
});
});
}
}
```
Until now no Angular users report this issue becuase in the `ngZone`, all
error will be caught and will not rethrow, so the event listeners afterward
will still continue to execute, but if the event handlers are outside of `ngZone`,
the error will break the execution.
This commit catch all errors, and after all event listeners finished invocation,
rethrow the errors in seperate `microTasks`, the reason I am using `microTask` here
is to handle multiple errors case.

This commit simplifies a regex used in angular.io's search WebWorker. It
also updates some comments to add more context on what the code does.

constructor is no longer used. This commit removes the unused parameter
and also the corresponding argument from the `publish` script.

Previously, the `URLS_TO_REDIRECT.txt` file was expected to separate
URLs by a `\t` character. This could easily been mistaken for a regular
space and would often result in test errors when updating the file.
This commit updates the `URLS_TO_REDIRECT.txt` file and the
corresponding test helpers to use `-->` (potentially surrounded by
whitespace) as a separator for the URLs. This also gives a hint about
the "from" --> "to" relationship of the redirect URL pair.

Previously, the `URLS_TO_REDIRECT.txt` file was expected to not contain
any empty lines. This could easily result in test errors when updating
the file, since it is common for IDEs/editors to automatically ensure
there is an empty line at the end of a saved file
([example failure][1]).
This commit updates the test helpers to be able to cope with empty or
whitespace-only lines in `URLS_TO_REDIRECT.txt` by ignoring such lines.

AppHighlight directive from the example doesn't have myHighlight attribute.
It only has appHighlight property. So we should use appHighlight instead of myHighlight.
PR Close#41410
Currently if a component defines a template inline, but not through a
string literal, the partial compilation references the template expression
as is. This is problematic because the component declaration can no longer
be processed by the linker later as there is no static interpretation. e.g.
```js
const myTemplate = `...`;
TestCmp.ɵcmp = i0.ɵɵngDeclareComponent({
version: "0.0.0-PLACEHOLDER",
type: TestCmp,
selector: "test-cmp",
ngImport: i0,
template: myTemplate,
isInline: true
});
```
To fix this, we use the the resolved template in such cases so that
the linker can process the template/component declaration as expected.

With the introduction of the partial compilation, the Angular compiler's
existing `parseTemplate` method has been extended to pass through multiple
properties purely in favor of the partial compilation.
e.g. the `parseTemplate` function now accepts an "option" called `isInline`.
This option is just passed through and returned as part of the `ParsedTemplate`.
This is not ideal because the `parseTemplate` function doesn't care
whether the specified template was inline or not. This commit cleans
up the `parseTemplate` compiler function so that nothing needed only
for the partial compilation is added to it.
We introduce a new struct for additional template information that
is specific to the generation of the `declareComponent` function. With
that change, we can simplify the component decorator handler and keep
logic more local.

We have several tests which use system.js, this means that we cannot use NGCC with `--create-ivy-entry-points`, also we need to process UMD bundles since our system.js configurations use UMDs.

This adds string literals, number literals, `true`, `false`, `null` and
`undefined` to autocomplete results in templates.
For example, when completing an input of union type.
Component: `@Input('input') input!: 'a'|'b'|null;`
Template: `[input]="|"`
Provide `'a'`, `'b'`, and `null` as autocompletion entries.
Previously we did not include literal types because we only included
results from the component context (`ctx.`) and the template scope.
This is the second attempt at this. The first attempt is in
1d12c50f63 and it was reverted in 75f881e078150b0d095f2c54a916fc67a10444f6.

This ensure that the name of the lazy chunk remains the same during updates. When not using `namedChunks` the id of the bundle is set to "deterministic", which means that the bundle name changes whenever the bundle is updated.

The `ViewportScroller` figures out which element to scroll into view using `document.getElementById`. The problem is that it won't find elements inside the shadow DOM.
These changes add some extra logic that goes through all the shadow roots to look for the element.
Fixes#41470.

When determining whether to run an animation, the `TransitionAnimationPlayer`
checks to see if a DOM element is attached to the document. This is done by
checking to see if the element is "contained" by the document body node.
Previously, if the element was inside a shadow DOM, the engine would
determine that the element was not attached, even if the shadow DOM's
host was attached to the document. This commit updates the `containsElement()`
method on `AnimationDriver` implementations to also include shadow DOM
elements as being contained if their shadow host element is contained.
Further, when using CSS keyframes to trigger animations, the styling
was always added to the `head` element of the document, even for
animations on elements within a shadow DOM. This meant that those
elements never receive those styles and the animation would not run.
This commit updates the insertion of these styles so that they are added,
to the element's "root node", which is the nearest shadow DOM host, or the
`head` of the document if the element is not in a shadow DOM.
