Bug in setting cautionary clef color

Version 5.1.21.2098 (Feb 22 2024)
When setting a color (in my case: alpha channel to 0, but any color) to a cautionary clef at a system’s end, this setting is not being respected. I can enforce it by touching the cautionary clef’s customary scaling (eg. to 99% and back or just by toggling the scaling switch forth and back). With that, the information about the colour is being accepted as well.
Seems like the color setting dialog doesn’t confirm/write the changes to the clef object, but setting the scale does it (thus also updating the color information).
I have created a video, where you can see the behaviour.
For use cases like mine (see video) I would appreciate the possibility to just switch off cautionary clefs in general or on a case by case base, but I didn’t find a better solution than making it invisible. Is there something I miss?
