Room avatars not loading

[Chirunos]

Describe the bug

No room avatars load when using Extera in one of my servers. Other kinds of media seem to work without issues.

This does not happen when using a different client (nheko 0.12) or when using a different server (mozilla.org, also on Synapse 1.130).

Reproduction

1. Find a room with an avatar set
2. Observe lack of it

Expected behavior

Room avatars load normally

Platform and versions

1. OS: Linux Mint MATE 22.1
2. Browser: Firefox 140.0b5, Brave Beta 1.80.100
3. Extera version: 1.0-DEV-8XZ2H (extera.officialdakari.ru)
4. Matrix homeserver: sulian.eu (Synapse 1.130)

Additional context
