I cannot edit the address bar in Safari once a web page is loaded
I'm using Safari 26 on a Mac Studio. If I enter a search term in an empty Safari address bar, like for here, it works. But once loaded I cannot edit the search bar, select the text, or do anything with it. I just get the popup box you see in the screenshot. On my MBP using the same settings and the same Safari version it works per usual. I can highlight say "discussions" in discussions.apple.com in the address bar to anything I want.
I've restarted and cleared caches, etc.
Searching by typing in the address bar works as normal in all my other browsers.
I've disabled all Safari extensions.
Thanks
Mac Studio, macOS 15.7
