State: closed
Merged: Yes

Summary of the Pull Request

Currently, while in IME mode, selections with the Emoji/Kaomoji/Symbol Picker (which is brought up with win+.) are not displayed until the user starts a new composition. This is due to the fact that we hide the TextBlock when we receive a CompositionCompleted event, and we only show the TextBlock when we receive a CompositionStarted event. Input from the picker does not count as a composition, so we were never showing the text box, even if the symbols were thrown into the inputBuffer. In addition, we weren't receiving CompositionStarted events when we expected to.

We should be showing the TextBlock when we receive any text, so we should make the TextBlock visible inside of TextUpdatingHandler. Furthermore, some really helpful discussion in #3745 around wrapping the NotifyTextChanged call with a NotifyFocusLeave and a NotifyFocusEnter allowed the control to much more consistently determine when a CompositionStarted and a CompositionEnded.

I've also went around and replaced casts with saturating casts, and have removed the line that sets the textBlock.Width() so that it would automatically set its width. This resolves the issue where while composing a sentence, the textBlock would be too small to contain all the text, so it would be cut off, but the composition is still valid and still able to continue.

PR Checklist

Validation Steps Performed

Tested picking emojis, kaomojis, and symbols with numerous different languages.
