Create new room dialog disappears unintentionally

[libexus]

Description

When creating a new room and choosing the room type "Public Room" the dialog suddenly closes but then appears inside "Explore rooms"

Steps to reproduce

Edit: This happens only if you have no Space selected

• click on "create new room" from your room list
• try to change the room type to "Public Room"
• the dialog closes
• now open "Explore rooms"
• the dialog appears there (but you still can't create a public room)

I can repro the dialog crashing

Looks like a regression caused by spaces
