[Minor forum request #2] Highlight selected feedback button on posts you've used them for

vsrs_au

When we click a feedback button on a post, there's no way to tell later on whether you used that button or not. Immediately after clicking it, you can see the number go to 1, or increment, but then later on you might forget which button you used for that post, and you have to click it once or twice to check. It would be a nice QOL update if these feedback buttons were highlighted if you'd previously clicked on them.
