To Recreate: Simply click anywhere on the player and the RELEASE CLICK over the title. This will create a tooltip which hovers over everything, on every tab, until the end of time. This has been a bug since I started using Roll20 in 2016. Yes! Almost 10 years. I have made posts about this before to no effect. Easy to recreate, easy to fix, it's so annoying having to refresh the browser and reposition the page every time. Come on devs.
