1. When the select-kit body is rendered, it defaults to being displayed under the triggering select-kit header, unless...
there isn't enough space between the bottom of the select-kit header and the bottom of the viewport
&
there's enough space on top of the select-kit header, and in that case, we render it on top.
2. We give it a bit of padding on top, so it never renders below the header on the Z-axis.

3. If there isn't enough space between the bottom of the viewport and the bottom of the select-kit header, and there isn't enough space between its top and the bottom of `d-header`, it renders at the bottom of the select-kit header.
In theory, number 3 above rarely ever happens. However, it can occur in the case of the user preferences page in combination with a large select-kit body (many categories).
The select-kit body then renders below the trigging select-kit header, but it's cut off. Users won't be able to see the entire select-kit body.
Here's an example

This PR adds a "prevent overflow" modifier to Popper. What it does is that it handles the case above.
If there's not enough space below the select-kit header or above it, render the select-kit body below the select-kit header BUT... anchor it to the bottom of the viewport.
Here's what that looks like
32cd1639bb.mp4
After this fix, even very large select-kit bodies will always be on the screen.
Please note that this PR has no impact on either number 1 or number 2 above, and those will continue to function as they currently do.
The only downside here is that the select-kit body might cover the select-kit header if it needs to be anchored at the bottom of the viewport, and it's very large. However, between that and not being able to see all the options, I think it's a fair compromise. There's only so much space in the viewport.
This PR ignores mobile because we have a different placement strategy. We use `position: absolute`... so, users can scroll the viewport if needed.
More precisely, if popper can't position something at the bottom, it will automatically attempt to position it at the top. However we should ensure it doesn’t consider the space under the d-header as valid space, when header's height is taken into consideration if top space is not enough, we should force bottom, and flip it back.
This logic is not necessary on modals as the d-header is not present.
* FIX: allows more precise placement strategy on mobile
- default to absolute on mobile, fixed on desktop
- allows to set a global `placementStrategy` or a specific to each view `mobilePlacementStrategy` `desktopPlacementStrategy`
This is mainly used to allow a proper composer-actions positioning in mobile.
Note this commit also fixes a mouseDown event which could propagate quote-button event and cause the composer to close full screen on mobile
* mobile only
Calling `window.getComputedStyle` during initialization causes the browser to pause and 'Recalculate Style'. On my machine, this adds about 7ms to boot time. Instead, we can check for the `rtl` class on the html element, which is added by the server, and doesn't require computing styles.
Major changes included:
- better support for screen readers
- trapping focus in modals
- better tabbing order in composer
- alerts on no content found/number of items found
- better autofocus in modals
- mini-tag-chooser is now a multi-select component
- each multi-select-component will now display selection on one row
On some modals the main/primary input field is a select-kit component (like `{{email-group-user-chooser}}` on the assign modal), so it makes sense to allow select-kit to steal focus on modals like these. This PR adds an `autofocus` option (default false) that allows select-kit to steal focus when it's rendered.
This PR is the first step towards replacing our `{{user-selector}}` and eventually deprecating and removing it from our codebase. Some of `{{user-selector}}` problems are:
1. It's called `{{user-selector}}`, but in reality in can also select groups and emails.
2. It's an Ember component, yet it doesn't have a handlebars template and uses jQuery to render itself and modify the DOM. An example of this problem is when you want to clear the selected users programmatically, see [this](6c155dba77/app/assets/javascripts/discourse/app/components/user-selector.js (L179-L185)).
3. We now have select kit which does very similar things but a lot better.
This PR introduces `{{email-group-user-chooser}}` which is meant to replace `{{user-selector}}`. It extends select kit and has the same features that `{{user-selector}}` has. `{{user-selector}}` is still used in a few places in core, but they'll all be replaced with the new component in a separate commit.
Once `{{user-selector}}` is not used anywhere in core, it'll be deprecated and then removed after the 2.7 release.
We want to wrap the `Ember.run.debounce` function and internally call `Ember.run` instead when running tests.
This commit changes discourseDebounce to work the same way as `Ember.run.debounce`.
Now that `discourseDebounce` works exactly like `Ember.run.debounce`, let's replace it and only use `DiscourseDebounce` from now on.
Move debounce to discourse-common to be able to reuse it in different bundles
Keep old debounce file for backwards-compatibility
eslint --fix is capable of fix it automatically for you, ensure prettier is run after eslint as eslint --fix could leave the code in an invalid prettier state.
