Steps to reproduce the problem:
1. Create a div with contenteditable="true" and the role="textbox"
2. Turn on ChromeVox classic
3. Type characters in the content editable div without adding a newline

What is the expected behavior?
ChromeVox should only verbalize the just added character.

What went wrong?
ChromeVox verbalizes the entire first line each time a character is added.
