Inspect the source lifecycle properties
OBS documents separate browser source options to shut the source down when it is not visible and to refresh it when the scene becomes active. The first can unload the page when hidden or absent from the active scene; the second can reload it on activation. If an overlay timer or permitted browser based media demonstration starts again after a scene change, inspect those settings before assuming that the remote site disconnected unexpectedly.
Compare one deliberate scene transition
For an original local test, use a harmless page with an obvious counter and record the relevant properties. Change away from its scene and return, observing whether the page retained its state or restarted. Change only the property being investigated for a later comparison. Keep visibility and activation actions clear in the record, since manually refreshing the source is another operation and would make a restart unsurprising.
Choose behaviour for the actual production task
An overlay which must begin fresh each time can need different settings from a persistent display which should continue across scene changes. Verify resource use and the intended state instead of declaring one choice universally correct. Do not give an untrusted page unnecessary permission to read or modify OBS settings. This article concerns a local source lifecycle and does not establish streaming account status, authorise commercial programme capture or promise identical behaviour in every browser outside OBS.
