Submit button has default color, but should use custom color

[hartsberger]

Steps to reproduce

1. Try to login and choose TOTP
2. The button below the one time code textfield shows the default NC blue.
3. (If you hover over the button, it shows the custom color, defined in our instance. )

Blue button:

Custom color button:

Seems like the guest.css is overwriting the custom color in this case.
I am not sure if this has to do with the guests app (enabled).

Expected behaviour

Show the button in the custom color.

Actual behaviour

Shows NC default blue as color.

Dup of #1006 and apparently fixed in the meantime.

Beware you are running a version of Nextcloud that has reached end of life: https://github.com/nextcloud/server/wiki/Maintenance-and-Release-Schedule

Sorry, I did not find that issue before opening my own.

Thanks for the hint, I know that I am a bit in delay 😬
