It's not ScriptingBridge, it's Music.
It's broken with AppleScript, it's broken with Shortcuts, it's broken with 3rd party AppleEvents software such as py-appscript, it's broken with ScriptingBridge. There are a variety of bugs, of which this is just one.
If it were just AppleEvents or ScriptingBridge I'd assume the bitrot had just finally caught up to us, but the fact that Shortcuts is equally broken tells me that something is actually broken here and might get fixed. I would recommend filing a feedback.
