<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This probably deserves a comment as to why we're doing a subscribe here, but we also have other logic for subscribing to the bridge a channel is in.
Actually, if this works, then we might be able to get rid of the other logic. This method is certainly a lot simpler.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'll add the comment with some explanation. I'd rather keep both because by removing the other mechanism for automatic bridge subscriptions, you risk causing the opposite problem of missing the ChannelLeftBridge event since the message may still be in flight when the subscription is removed. A possible way to mitigate that would be to wait for the appropriate topic(s) to flush.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This fixes an issue where a Stasis application running over ARI and subscribed to ari/events could miss the ChannelEnteredBridge event because it did not subscribe to the new bridge fast enough.
To accomplish this, it subscribes the application controlling the channel to the new bridge before adding it to that bridge which required the stasis_app_control structure to maintain a reference to the stasis_app.</pre>
