iFrame: Reply in direct message, cannot go back to general chat

Description:

Cannot go back to general channel from replying to direct message in an iFrame

Steps to reproduce:

1. Use the "Reply in Direct Message" on a message in general chat
2. Room opens
3. Here you don't have any options to close the room and go back to general chat

Expected behavior:

An option to go back to general chat. Or is there a way to disable this functionality? We could even disable the message actions menu, it's not really needed in our case. I couldn't find any of these option to disable in the admin area.

Actual behavior:

You are in the direct message room and there is no way you can go back, even if you use commands like /leave.

Trace the message action and room navigation entry points; done means users can return to general chat or the relevant action can be disabled through an available setting.
