> While fixing ASTERISK-24988 did fix the race condition where a channel is bounced out of the Stasis application due to the WebSocket being connected but the application not being registered, it has introduced another problem where a StasisStart event is not emitted for a channel.
> Consider the following scenario:
> # A WebSocket connection is started. Before the upgrade response is sent back, we register the Stasis application with {{res_stasis}}, such that any channel that joins after the upgrade notice is accepted.
> # A channel hits the dialplan application and is put into Stasis, as the application is registered
> # *HOWEVER* - because the WebSocket TCP connection isn't made, the StasisStart event cannot be sent. This causes the channel to enter Stasis with no notification to the (eventually) connected application.
> Logs showing this are attached. Note that this was also caught by the same TalkDetect test in the TestSuite.
