Japanese IME issue on iOS Safari, using Angular and ngx-quill

[VitBazylchik]

During using ngx-quill and Angular I've faced an issue with Japanese IME in iOS Safari. The solution was found in current library. In Composition class there is the compositionend event handler. Handler of this event is executed inside queueMicrotask function due to Webkit bug. But for iOS for unknown reasons (I guess, due to using manipulations with zone.js) there is still not enough time to wait for DOM changes. Changing queueMicrotask to zero setTimeout solves an issue.
My proposition is to make a change mentioned above.

Steps for Reproduction

1. Open Quill example in iOS Safari https://github.com/killerCodeMonkey/ngx-quill-example
2. Use Japanese language (I believe, any IME should reproduce it)
3. Try to use IME on any editor there

Actual behavior: Text freezes, no value emitted outside. Impossible to delete inserted by IME text.

Platforms: iOS, Safari
