(Toolkit :: Autocomplete, defect)

Description

[Alice0775 White]

The suggestion drop down is closed When the user start typing text with IME.
And The suggestion drop down is re-opened when user finished conversion of IME.

It is annoying behebiour because it disturbs my eyes. 
And the annoyance is remarkable since Since landing the new Search UI.

1. Open any input field which is enabled autocomplete or Searchbar
2. Turn on IME
3. Type text and composition start, [にほん] ;where [] in progress composition by IME
   ---- Suggestion is hidden
4. Conversion IME, 日本
   ---- Suggestion pops up
5. Append text and composition start  日本[けんちく]
   ---- Suggestion is closed
6. Conversion IME 日本建築
   ---- Suggestion pops up

This behavior is by design. See bug 165055.

Applications cannot know when IME shows candidate window or suggest window. Therefore, we stop autocomplete between compositionstart and compositionend for preventing the autocomplete window covers IME's window.

I mark this as INVA. However, if you have some idea for better behavior, feel free to comment here. If it's really better idea, we should take it.
