Hi all,
I’m interested in whether it’s known how heartbeats are handled by different browsers. I ask because, with the default heartbeatInterval in Safari, it seems that whatever javascript initiates the HEARTBEAT request is not triggered when the browser tab is in the background. When I set the heartbeatInterval to 30 seconds, Safari seems to now always send the heartbeat as expected.
Is this explainable? Are there other quirks in other browsers?
Best, Dan.
