19272 - [IME][PP][dogfood]BACKSPACE key will move caret to one line above before convert

Status: VERIFIED DUPLICATE of bug 19130

(Core :: Internationalization, defect, P3)

Description

[Teruko Kobayashi]

You can delete Japanese characters before commit by using Backspace key.
In composer, you can delete them, but the caret will move one line above.

Steps of reproduce
1. Open Composer
2. Turn on IME
3. Type 3 Japanese characters (at this time, do not hit enter to commit)
4. Hit Backspace key 3times to delete whole characters

Notice that the characters were deleted, but the carret move to at the beginning
of the one above line.

If you use Backspace key to delete character before commit at the first line of
Composer, the caret is gone.  You cannot type any characters in Composer at all.
You have to quit Composer and start it again to type characters.

This is similar bug to 19130, but this happens in Windows only.
Tested 111808 Win32 build.

same as 19130. When the IME commit empty text event in the beginning of a text
node. The rule system or edit txn code confused. Mark it as dup of 19130.
