Realtime subscriptions can fail silently in WebGL builds

I noticed that realtime subscriptions can fail silently in WebGL builds.
When I leave the tab (which runs the Unity build) in the background for a while and come back to it, the subscriptions no longer trigger. When I check the logs, I can see that the disconnect callbacks were never triggered.

I suspect that either the browser, PocketBase, or my router drops the connection after it has been idle for too long, and that the Unity-side code is effectively "paused," preventing the disconnect callback from firing.

My workaround for this, at least for now, is to have a MonoBehaviour that tracks all active realtime subscriptions and first unsubscribes and then resubscribes to them when the application regains focus. It’s a bit of a hack, but it works.

It might be the browser. There is a retry mechanism, but if the disconnect callback is not triggered, the retry will not be triggered either. I tested the manual disconnection on my side and it is working. Would be great if you can test it to :).
