Reproduction Steps:

3.

I keep typing away in the message body field and randomly ChromeVox starts repeating the entire line for each key press. If I continue typing away, it does stop doing that. I can definitely reproduce it fairly consistantly. It sometimes even plays the earcon in my left ear. I can't be certain but I suspect it is reading the previous line when the line wraps to the next line. Just a guess.

I can repro everytime I am composing a message or replying to it.

This doesn't seem to be specific to Gmail and also appears in multiline text fields.
