Calls not working in macOS desktop app (4.11.2)

[awkitsune]

Describe the bug

Can't connect to voice rooms in Cinny desktop app 4.11.2
with error in console Error: Your browser does not support WebRTC.

Electron seems to somehow break WebRTC support with WebKit

Reproduction

1. Open Cinny desktop app on macOS
2. Try to connect to any voice room
3. Infinite waiting of join

Expected behavior

Should be able to join voice room from desktop app

Platform and versions

1. macOS Sequoia 15.7.5 (24G623)
2. Safari 26.3 (20623.2.7.18.1) (calls working)
3. Desktop app 4.11.2 (calls not working)
3. Homeserver `yubinkyoku.azihran.space` (does not affect anything in this case)

Additional context

But I perfectly can do this in web app with Safari 26.3 (20623.2.7.18.1) (useragent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/26.3 Safari/605.1.15" = $1) without any console errors and stuff

Checking out user agent it seems Cinny desktop is using WebKit on macOS (might be wrong)
"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko)"

As you can see, the WebKit is basically the same version, but Electron seems to somehow break WebRTC support with WebKit

I also could observe this issue on arch with wayland. Possibly related to #545 ?

See this with the app image on Debian and PopOS distros too

I am on bazzite using flatpack and I am seeing the same thing.
