Fixed the bug where occasionally the notification popout appears under the body

[titonova]

Occasionally, the megaphone popout might appear under the body and navbar, depending on the structure of the navbar, usually if the navbar is fixed/sticky or something. Simply changing the z-index does not work.

Luckily, livewire v3 provided a simple functionality to fix it, @teleport

@mikebarlow If you are wondering, I deleted the previous fork, so the previous exact pull request was deleted as well.
