Error handling UX inconsistency

[aschmahmann]

If I go to https://bafkrgidbb4z3r27x5r4v7arkivh3quqvnlx6kc7azobsmm4kqhgxjaaymq.ipfs.inbrowser.link/ I get a 504

If I refresh the page I still see https://bafkrgidbb4z3r27x5r4v7arkivh3quqvnlx6kc7azobsmm4kqhgxjaaymq.ipfs.inbrowser.link in my address bar, but I see the inbrowser.link page. As an aside if you put a CID into the page and press enter you'll get an error (correctly) because https://bafkrgidbb4z3r27x5r4v7arkivh3quqvnlx6kc7azobsmm4kqhgxjaaymq.ipfs.inbrowser.link/<someCID> is invalid.

If I then go and delete the CID portion of the URL and hit enter I get a 401 instead:

This was using Chrome Version 138.0.7204.97 (Official Build) (64-bit)

Related to #816, although might be independent

Yes, I have also noticed this behavior, with the invalid address in the browserbar, even with ordinary CIDs.
