MudPopover: Fix Z-Index edge cases

[versile2]

Description

Resolves #10723 by recalculating MudOverlay position when a nested popover is closed.
Resolves #10727 by not allowing default css value to lower the js z-index value assigned.

Visually, Unit tests still pass

When launching the test viewer I get:

TypeError: Cannot read properties of undefined (reading 'getAttribute')
Stack trace:

at

const tickValue=parseInt(popoverContentNode.getAttribute('data-ticks'))

EDIT: Not fixed with full rebuild + cleared cache.
