Steps to reproduce:
Open a new tab in fullscreen (this does not work on the notes tab or start page, it seems.)
Click on the downloads icon, and show a file (magnifying glass)
Address bar field pops up unexpectedly.
The address bar does not show up when you show a download
Orion and macOS:
Orion Version 0.99.108.1-beta (WebKit 613.1.10)
macOS Version 12.0.1
I am using two screens, so the file popped up on the second one. Nothing wrong on that front.
