OK, I thought this was weird. My default browser is Safari Tech Preview. I saved a webpage to my desktop from this browser. But when I clicked on it on my desktop it opened up in regular Safari! How do I get it to open up in Safari tech preview? That shouldn't have happened, right? Under system prefs Safari Tech Preview is definitely the default browser.

MacBook Pro - Catalina 10.15.7
Safari Tech Prev 14.2
Safari 14.1.1
Firefox 94.0.2
iPhone 7 Version 14.1
