And even if it fails for some reason, it's probably better to have a button with an incorrect icon (that users would notice and report) than no button at all.

Removed that failure check in v2, thanks a lot for your always helpful reviews :-)

Oh, now I found !1857 . That one looks really great. Merging my patch would probably be annoying for Vladislav when rebasing, so if there's a chance of his patches making it across the finish line before wine 9.0, I think it would be better to wait for that and put this merge request on hold.

Closing in favor of !2993 . Thanks for your work on this, Vladislav! And thanks, Esme, for the reviews.
