[Bug]: Theming broken in 32.0.9 #60146

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

Since the update to 32.0.9 the custom images set at /settings/admin/theming are not shown in the Nextcloud UI anymore. This affects:

• Logo
• Background and login image
• Header logo
• Favicon

default	custom image

For new images, it doesn't seem to make a difference whether you are using SVG, PNG or JPG images - they are all not working.

Custom non-SVG images, that were set before the update to 32.0.9, seem to still work - as long as you don't change them.

Steps to reproduce

1. Set custom images at /settings/admin/theming
2. See how they are not displayed in the design of your Nextcloud

Expected behavior

Custom images should work.
