Describe the bug
In Japanese text (kana) input mode, writing some text, sometimes suddenly cursor jumps to top line.
At that time, many errors appear in the console log like this:

Additional context
Maybe, this issue's cause is event called each KeyDown.
In Japanese text input mode, the flow is as follows:
input -> convert -> decision
It appears that Event is called each "input", but perhaps should be called after "decision".

I reproduced this issue.

Change the input mode to Japanese text.
Input any text. In this example "あいうお".
Press Delete key.
Input any text. In this example "え".
-> Cursor jumped to beginning point, and the previously entered strings is entered together.
