Full Screen mode needs to end when switching apps
Steps to reproduce (seen on Premiere Pro 25.3.0 (Build 84) on macOS Sequioa 15.6)
1. Press Command-` to enter full screen mode
2. Press Command-tab to switch to another app
3. I'm still seeing the full-screen video from Premiere Pro and I've got no visible way to regain control of the system. The usual keyboard shortcuts of Escape or Command-` will no longer work since I'm out of Premiere.
The workaround is to realize that this has happened and Cmd-Tab back to it (even though the task switcher will no longer display), but I'd regard this as a bug. There's no reason why the full-screen video would want to remain once I've used the task switcher to move focus to another app, and it absolutely shouldn't be on top anymore.
