So today I updated my iPad pro to 15.6 just released. I did try it again hoping it might have been fixed.
Same problem
Then I did try Firefox from App Store version 102.1 and I am seeing the same behavior as Safari did.
Next, I downloaded Brave from the Apple Store version 1.40, and right away I had an even worse issue.
When I try to connect to the initial status landing page I only got this screenshot attached. I did try to close the Brave browser, clear the cache, and even restart the iPad just so I am not being asked here if I did try it.
Under Brave, I only see some parts of the page. Since Fullscreen and others are not available I was not able to test it.
