On the session recording interface do not automatically start the next recording when one is played through

Feature request

Is your feature request related to a problem?

Moving around in large recordings is generally slow. If you are trying to seek to a point close to the end of a 3 hour recording, then you will load for 10s of seconds. Seeking is also imprecise and it frequently happens that I'm trying to seek, it loads then I'm very quickly moved to the next recording, which unloads all context for the recording I'm trying to seek in.

If the recording I jump to is also large, that is an other extra loader and freeze.

Describe the solution you'd like

I'd like the session recording screen to not autoplay through multiple recordings, only the one I click on. Then I can still seek on the bottom and scroll through the events on the right side even if the recording just finished.

I have no use for autoplaying all recordings but I imagine some users do, so maybe this could be a setting on the screen, but I think it should be the default.

Describe alternatives you've considered

A general performance improvement would also greatly mitigate the issue, but I imagine that to be a much bigger technological challenge.

The issue does not name a file or test; start by locating the session recording screen and its playback-completion handling. Verify the current behavior with multiple recordings, then confirm that playback stops after the selected recording while seeking and event browsing remain available after it ends.
