Client crash (React error #300) when clicking the Rejoin bar for a deleted temporary voice channel

Observed behaviour

The client crashes instantly with Minified React error #300. This occurs because the application attempts to render a component into a target container that was removed from the DOM when the bot deleted the channel.

Reproduction steps

Join a temporary voice channel (created by a bot).
Leave the voice channel (which triggers the bot to delete the channel).
Wait approximately 2 minutes until the "Rejoin" notification bar appears at the top of the app.
Click the Rejoin button.

Details

Expected behaviour The client should verify if the channel still exists. If the channel is deleted, it should remove the "Rejoin" bar or show a "Channel not found" notification.
