We need to investigate the time it takes to create a preview session (It's gotten worse?) #1347
Description
This is likely a regression of some kind, it was previously instant.
It was taking longer before because we would do:
- Create a new preview session
- Immediately after requesting the creation of it, send N configuration updates to the session that would require it to be completely recreated.
The fix was to collect all initial settings we wanted first and then create the preview session with all of the settings passed during initialization.
