) Summary: Pull Request resolved: facebook#45545 ReactInstance creation in bridgeless returns a callback that requires dispatching on the UI thread to complete the init. If that thread is busy (eg with other startup tasks), we delay starting the initial surface unnecessarily. This diff adds an experiment to return early from that startup task to allow follow-up tasks to be scheduled on the JS thread without waiting for lifecycle changes to have been applied.
