Custom SVGs are not shown

Nextcloud version (eg, 20.0.5): 21.0.2
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25): Nginx 1.18.0
PHP version (eg, 7.4): 7.4

The issue you are facing:

I wanted to customize Nextcloud using the Theming app so I uploaded SVG Logos, but these SVGs are not visible. When I download and open them using the same request as shown in the Networking Dev Tools I can see that there is nothing wrong with the file. It is uploaded correctly and the file is not corrupted

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Download and Setup Nextcloud 21.0.2
  2. Install php7.4-imagick
  3. Install libmagickcore-6.q16-3-extra
