Note that fullscreen breaks command tab. Create two safari windows (or FF, Chrome, doesn't matter - except that Apple shipped safari, so we'd expect that to be able to render a window to the screen correctly).

Full screen one. Switch to the other. Now, use just cmd-tab and cmd-` to get to the full screen safari window (cmd-` switches between windows in the same application, which is literally never the right thing, but I digress).

For what it's worth, the third party tool 'altTab' mostly fixes this.

Bonus MacOS UI bug: I had to exit altTab to confirm they still hadn't fixed cmd-`. When I re-opened it using cmd-space, finder defaulted to the version in ~/Downloads instead of /Applications, then read me the riot act about untrusted software trying to change accessibility settings.

One more thing: I'm still not using MacOS 26, so all my complaints are about the "last known good" release.
