Problems with Chinese Keyboard Pinyin (Mac Default one & Chinese IME in IE11) with Quill API updateContents

[WinMinTun]

Hi I have written a Quill Authorship module https://github.com/WinMinTun/quill-authorship
Mostly ok, but with some serious problem with Chinese Keyboard which I believe to do with Quill JS code. Some Chinese Keyboard which shows Pinyin popup has the error. (Mac Chinese keyboard, Chinese IME in Window). Other Chinese keyboard which does not actually write the English characters in the editor (before showing Chinese chars pop) like in Android Google Pinyin is ok.

Whenever I called this.quill.updateContents(authorDelta, Quill.sources.SILENT); in my module gets the following problems. Seems like cannot update the delta (to add author attribute) while showing popup.

UPDATE: Whenever there is a mutation regarding the attribute change to delta (to mark the authorship), the Pinyin pop up disappears. So basically I couldn't call updateContents to update the delta with author attribute without Pinyin pop up disappear. The next chars are ok because already set the authorship attribute to the first character, and I stopped calling updateContents then. Pls kindly help, I desperately need that authorship module!!

I fix it only only adding author attribute on compositionend for IME keyboards. But one more BIG issue appears, IME keyboards not working on collaborative editing. For example in Chinese Keyboard, when user type some English word 'w' and then Chinese words appear. At that time when others are changing the content, I will get redundant words. Refer to #2314
