Keyboard navigation commands and braille routing don't work as expected in the comment editor

Ref: #110408

I would expect the comment editor to behave just like a regular editor window, but in my case it is not. I don't hear screen reader feedback as I move through words and lines with the keyboard. Also, when I press a routing cursor key on my braille display, it does not move the cursor to the desired character.

Tested with NVDA and JAWS.

• Invoke the action to leave a comment in the current line
• Write some text
• Use ctrl+left and ctrl+right to move through words
• Use up and down arrow keys to move through lines
• If you have a braille display with routing keys, press a routing cursor key to move to a specific character in the text
