Backport #34438 by @silverwind
In the comment editor, there is a bug in Firefox where the scroll
position unexpectedly moves up, which is annoying. This is not
reproducible in Chrome and Safari. To reproduce here are some steps:
- Go into an editable issue
- Scroll page to bottom
- Focus the textarea and press Return many times, causing the textarea
to get a scrollbar
- Scroll page to bottom again
- Press Return once more
- Page should not scroll up.
This fixes the bug by adding a temporary margin, and I verified it works
in all browsers.
