In #37221 we disabled tsickle passes from transforming the tsc output that is used to publish all
Angular framework and components packages (@angular/*).
This change however revealed a bug in the ngc that caused __decorate and __metadata calls to still
be emitted in the JS code even though we don't depend on them.
Additionally it was these calls that caused code in @angular/material packages to fail at runtime
due to circular dependency in the emitted decorator code documeted as
https://github.com/microsoft/TypeScript/issues/27519.
This change partially rolls back #37221 by reenabling the decorator to static fields (static
properties) downleveling.
This is just a temporary workaround while we are also fixing root cause in `ngc` - tracked as
FW-2199.
Resolves FW-2198.

As of TypeScript 3.9, the tsc emit is not compatible with Closure
Compiler due to
https://github.com/microsoft/TypeScript/pull/32011.
There is some hope that this will be fixed by a solution like the one
proposed in
https://github.com/microsoft/TypeScript/issues/38374 but currently it's
unclear if / when that will
happen.
Since the Closure support has been somewhat already broken, and the
tsickle pass has been a source
of headaches for some time for Angular packages, we are removing it for
now while we rethink our
strategy to make Angular Closure compatible outside of Google.
This change has no effect on our Closure compatibility within Google
which work well because all the
code is compiled from sources and passed through tsickle.
This change only disables the tsickle pass but doesn't remove it.
A follow up PR should either remove all the traces of tscikle or
re-enable the fixed version.
BREAKING CHANGE: Angular npm packages no longer contain jsdoc comments
to support Closure Compiler's advanced optimizations
The support for Closure compiler in Angular packages has been
experimental and broken for quite some
time.
As of TS3.9 Closure is unusable with the JavaScript emit. Please follow
https://github.com/microsoft/TypeScript/issues/38374 for more
information and updates.
If you used Closure compiler with Angular in the past, you will likely
be better off consuming
Angular packages built from sources directly rather than consuming the
version we publish on npm
which is primarily optimized for Webpack/Rollup + Terser build pipeline.
As a temporary workaround you might consider using your current build
pipeline with Closure flag
`--compilation_level=SIMPLE`. This flag will ensure that your build
pipeline produces buildable and
runnable artifacts, at the cost of increased payload size due to
advanced optimizations being disabled.
If you were affected by this change, please help us understand your
needs by leaving a comment on https://github.com/angular/angular/issues/37234.

This commit updates payload size limits that are triggering errors after merging cda2530. That commit seems to contribute to the payload size increase, but all checks were "green" for the original PR (#35889), so it looks like it's an accumulated payload size increase from multiple changes. The goal of this commit is to bring the master branch back to "green" state.

With this changer we update the CLI size-tracking changes for uncompressed
main-es2015 file. This file is larger due to new emitted shape of
ES2015 classes in TypeScript 3.9, which are now wrapped in IIFE.

In 420b9be1c1 all style-based sanitization code was
disabled because modern browsers no longer allow for javascript expressions within
CSS. This patch is a follow-up patch which removes all traces of style sanitization
code (both instructions and runtime logic) for the `[style]` and `[style.prop]` bindings.
PR Close#36965
This patch is the first of many commits to disable sanitization for
[stlye.prop] and [style] bindings in Angular.
Historically, style-based sanitization has only been required for old
IE browsers (IE6 and IE7). Since Angular does not support these old
browsers at all, there is no reason for the framework to support
style-based sanitization.

Only refresh transplanted views at the insertion location in Ivy.
Previously, Ivy would check transplanted views at both the insertion and
declaration points. This is achieved by adding a marker to the insertion
tree when we encounter a transplanted view that needs to be refreshed at
its declaration. We use this marker as an extra indication that we still
need to descend and refresh those transplanted views at their insertion
locations even if the insertion view and/or its parents are not dirty.
This change fixes several issues:
* Transplanted views refreshed twice if both insertion and declaration
are dirty. This could be an error if the insertion component changes
result in data not being available to the transplanted view because it
is slated to be removed.
* CheckAlways transplanted views not refreshed if shielded by
non-dirty OnPush (fixes#35400)
* Transplanted views still refreshed when insertion tree is detached
(fixes#21324)

If there's an error during the first creation pass of a `TView`, the data structure may be corrupted which will cause framework assertion failures downstream which can mask the user's error. These changes add a new flag to the `TView` that indicates whether the first creation pass was successful, and if it wasn't we try re-create the `TView`.
Fixes#31221.
