* Fixes#4067 besides snackbar
Makes layout hierarchy more shallow to increase performance.
* Fix#4067 Feedback
Make sure quick_action_overlay appears on top and use horizontal chain in tab_header.
The previous solution would result in a crash because the passed in
viewTreeObserver that would trigger onPreDraw would be invalid.
The proposed solution is simpler and ensures we'll always use the right
viewTreeObserver.
`FragmentPreDrawManager` is general enough that can be used by other Fragments
also, so I've added it to the `utils` package.
* Fixes#4704. Overrides `setEnabled` for DeleteBrowsingDataItem to change view alpha when disabled and to toggle the checkbox `isEnabled` behavior based on the value provided.
* Updates CHANGELOG.md
* Removes unnecessary disabling of checkbox in DeleteBrowsingDataItem.kt
Updates CHANGELOG.md to reflect the component changed.
* For #4396 - Rename BookmarkInteractor methods
Following the naming model used in other Interactors this too will use reactive
method names in the form of "on..." instead of the previous imperative model.
Kept the imperative naming model for the methods from `SelectionInteractor` as
they are a new addition and I'm not sure about the future direction.
* For #4396 - Add a BookmarkController
It abstracts the Fragment behavior in a contract through which various
Interactors can inform about the specific View changes and can ask for
modifications in their container Fragment.
This contract and it's implementation - `DefaultBookmarkController` are the
result of extracting the container Fragment's business logic from
`BookmarkFragmentInteractor` in it's own standalone component.
* For #4396 - Refactored Bookmark related tests
Added a new `BookmarkControllerTest` tests class which complements the new
`BookmarkController` to ensure that it properly operates on `BookmarkFragment`
Also refactored the existing `BookmarkFragmentInteractorTest` to accommodate
`BookmarkFragmentInteractor`'s now more specialized behavior.
