My test notices setup:
2 regular block notices
1 floating notice
For the following screenshots, left side is logged in, right side is logged out.
First visit both titles show fine of course:
Dismissing the second notice and refresh the page the title hides for logged in but not logged out
If you go into the ACP and disable one of the two block notices the title goes away for both logged in and logged out:
Not a big deal but figured I'd report it.
