@jacekkarczmarczyk Thanks for looking at this issue, I add "persistent" property to the Dialog 1, this is the workaround I found. Now I remove the property and you can try again. The issue is remain.

This is effectively a duplicate of #7310, if the other dialog is not a child it counts as an outside click. The stackable service is needed to fix this.
