What are the known limitations of customizing the Plesk login screen background?

Question

What limitations exist when customizing the background for the login screen via Tools & Settings > Branding in Plesk?

3. Branding customizations are not included when migrating or restoring from a server-wide backup..

4. Images up to 2GB can be uploaded for branding purposes. However, images over approximately 50MB can significantly slow down the loading of the Branding page and login page itself. Managing performance issues related to large image files is the responsibility of the customer.

5. The dark theme may alter the background color (excluding pictures) in the preview. However, the actual background color remains unaffected.
