Files directly download from shared links instead of co-editing

[mmeeks]

Describe the bug
Someone shares an internal link to a document with me. I click on it, but instead of entering the document I get one of these three behaviors:

1. the file immediately downloads and opens locally - nice but no collaboration / cookie etc.
2. the file-view opens on the folder with the file highlighted but not opening
3. the file fails to load like this: Failure to Load Nextcloud Office #4139
4. the file actually opens corectly.

Chance of getting to 4. is quite a lot lower than it used to be, previously you would get 2. and 4. now I get lots of 1. and 3. as well as 2. - when really I want 4. =)

To Reproduce
