No room title is shown when opening room page (8 entities) and all 8 slots are used. Timing thing? #296

Describe the bug
When opening a room the title of the room is printed in the top of the page.
On an 8 entity page when all slots are used the room page title is never printed. Having 7 slots used the room title is printed. It feels like a timing thing. I've also seen that sometimes a slot that should have a light only shows the switch icon but the name of the light is never printed.
