Stops shooting after some time if page is in background

Looks like if I set it to shoot lots of images on an Android phone and switch apps, it keeps going for some time and then stops after 2-3 minutes or so. I suspect Chrome thinks the web app is inactive and eventually discards it to save resources, even though it's still doing an important long-running task.

I'm not sure what's the correct solution to prevent this - screen lock API (even though I don't care about screen being on)? Something else?

@tomayac is this something you could advise on?

It may indeed be tab discarding. In a surprisingly potentially related bug, the resolution (not documented on the bug thread) was to keep something with pending contenteditable edits open, which apparently serves as a way to prevent tabs from being discarded. This is not a very intuitive solution obviously, but for testing purposes, could you try if this addresses the symptom?

Oof. Yeah I could try that before next shooting session, but I hope there will be a better way 😅 Thanks, I'll subscribe to the bug. (UPD ah it was closed as wontfix, so probably not helpful; it was also about beforeunload which I don't use here anyway)
