Steps to replicate the issue:

• Using Vector 2022 (with tools moved to the sidebar) open https://de.wikipedia.org/w/index.php?title=Wikipedia_Diskussion:Kurier&action=history
• Click the thank button for different comments (once)
• Try to click „Danken“ / „Abbrechen“ (Thank / Cancel)

What happens?:

• Sometimes clicking „Danken“ / „Abbrechen“ works, sometimes it doesn't
• When zooming out (below the standard size) it works for all comments
• When hiding the toolbar there are no problems as well
• There are no issues using other skins

What should have happened instead?:

• Thanking (or canceling) should work on all comments regardless of the toolbar / zoom / skin

Other information (browser name/version, screenshots, etc.):

• See this screen recording showing the problem (using WeTransfer due to the file size)
• The same issues has occurred for me multiple times during the past couple of weeks, I just didn't have the time to report it until now
