No response to updates after prolonged wait time

[tingerrr]

Describe the bug
After a prolonged period where I did not edit any files, subsequent edits do not update the logs or preview at all.

To Reproduce

1. run typst-preview file.typ
2. wait for some time (5 minutes should be enough)
3. edit file and observe no update in logs or preview

Expected behavior
Edits continue to update the preview after I come back.

Another possibly related issue is that, when I force and update by running :w in helix, it'll work just fine, but after just a few seconds of inactivity it will stop responding to any real updates after I force one using :w.

Where using :w will cause the file to be written as it currently it's seen if it hasn't changed.

This is in the end quite annoying, as I need to restart typst-preview frequently.

EDIT:

In fact, it seems even weirder, once I encountered this issue at least once I can reproduce it instantly, even though they are completely separate instances. It seems, that it works for a while after freshly starting my PC or window manager and after a while it just doesn't anymore.

WebviewActor: received non-text message from websocket: Close(Some(CloseFrame { code: Away, reason: "" }))

This might be the root cause. The browser tab seems close the websocket. Can you provide browser logs? I will also try reproduce this when i leave work

I'm not sure, in the second log I sent you can't see that at all.

The browser logs are structured, so I opened them to the depth I deemed important.

Here too I noticed that regular updates work, then a non-update using :w without changes causes no update in the logs at all, and any subsequent writes don't either.

PS.: I didn't find a way to easily export the logs in firefox, sanitizing this myself was painful, surely there's a better way in case you need more logs.

The second log may indicates something might be wrong with file watcher.

[tingerrr]

So this may be a problem upstream at typst.ts? It seems the file watching is done using their CompileActor from what I could gather after a quick peek.
