Fix Quote Reply button on review diff

[jpraet]

Fixes #13762

This fixes the "Quote Reply" button on the code review diff page.

I also noticed the focusing of the text area wasn't working for the "Quote Reply" as well as "Edit". Something else is stealing the focus. I tried to work around that with event.stopPropagation() at first, but that caused other issues. Once I wrapped the focus code in a setTimeout(..., 0) it started working. Might not be the cleanest solution?

Something else is stealing the focus

Is there a autofocus element on the page? Also, you can try logging document.activeElement in the browser console to find the current focused element.
