Bugzilla

*Thank you for helping make Firefox better. If you are reporting a defect, please complete the following:* 

## What were you doing?

1. Visit  https://us.gozney.com/blogs/recipes/
2. Open devtools debugger (e.g. F12 and then click "Debugger" tab)
3. Press the key-combo for "Find in all files" (ctrl+shift+f for me)
4. Type a string like "def" and hit Enter.  ("def" is nice because it triggers lots of hits for "default")

## What happened?

A circular throbber spinner-image appears at the right edge of the searchbar; it renders with an unexpected square "frame" around it (which also spins).  See attached screenshot (and upcoming screencasts).

## What should have happened?
No square frame.

## Anything else we should know? 
* I'm using Nightly 106.0a1 (2022-08-24) (64-bit) on Ubuntu 22.04
* I don't have any pixel scaling (not high-DPI/retina). i.e. my `window.devicePixelRatio` is 1. Haven't tested with other DPI configurations / pixel ratios yet; but I can imagine this *might* go away with higher pixel ratios (otherwise I imagine we would have noticed & fixed this by now).
* I can reproduce in a fresh profile. It's a bit more noticeable with a dark theme, but you can see it very-clearly with a light theme as well.
* This seems to be a regression. In builds from before the regression, I see a very tiny amount of the same fringe, but it's just a few pixels rather than a full square.
