Weird bug when using transitions and a $navigating spinner together

[Nightloewe]

Describe the bug

When switching pages, there is a bug happening when the layout contains some code to show a loading spinner on $navigating != null and the page we are navigating from contains a transition. The transition then happens, but stops and the DOM is not updated to remove the old page and render the new page.
