Describe the bug
After updating recently, the spotify widget i'd made myself and have been using the past year without suddenly started disappearing frequently. sometimes button would remain with no icon, sometimes button disappeared altogether. i rolled back to 3.217 and it's back to normal, so its definitely tied to later versions. was something changed in how buttons can have their content modified by an applescript?

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

Could you send me an export of your preset? ( So far I haven't heard of issues with the Apple Script widgets in the current versions. Maybe it's some specific setting.
