544778 - [TSF] Implement ITfTextEditSink

Status: NEW

(Core :: DOM: UI Events & Focus Handling, enhancement, P5)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

We should implement ITfTextEditSink interface because it's useful. We can know the timing of each edit completing by OnEndEdit method. So, we can simplize the composition handlers.

I've not found TIP which needs this feature. So, this must be optional. No other bugs shouldn't blocked by this.

Moving all open keyboard/IME handling bugs to DOM: UI Events & Focus Handling component.

According to Chromium's code, we can make TSFTextStore::OnUpdateComposition() with removing its complicated helper methods. However, that means that retrieving content data between OnUpdateComposition() and OnEndEdit() from TIP would be changed. This might break some TIPs if they do some hack for Gecko. So, without some incompatibility with existing TIPs, we shouldn't do this.
