[SOLVED] Layout broken (logged in) in Microsoft Edge

Running on 14.0.4
Clients including firefox and chrome on linux and windows all seem to work as the should.
Using MS Edge however, the layout of /apps/files is completely garbled.

Is this a known issue?

Using the browser console does not seem to reveal relevant info (I think this error is only related to device emulation in the dev tools).

I have not touched the stock theme/CSS apart from
.lost-password-container #lost-password, .lost-password-container #lost-password-back { color: unset; }
to make it visible on my light background.


Are there any other things I can try to debug this?
Thanks in advance!

Seems to be fixed at least with NC 16.x.
