I have this problem too on Ubuntu Mate 22.04 with Yaru-Light theme. It happens with some of the icons on plank, like Firefox-snap version, not the Firefox-ESR version. Very annoying indeed.

I had an indicator that the application i was clicking on was open and when i clicked it, it would be restored if it was minimized and it will be minimized if it was maximized or just being shown on the screen but on this version, even if the application is minimized or maximized, when i click on its icon, first of all, i can't see that "application open" indicator below its icon anymore(Only below the Plank icon) and second of all, Plank will open a new instance of that same application. I recorded a video showing you what i am talking about. And also, sometimes when i click on the icons on the dock, i won't have that visual feedback, that "little jump" of the icon i click. That's very important as well otherwise, i think nothing happened. That's all. I really like Plank and it is a great application. Thanks for it.
