fix: bring native popover to top layer for special cases - #2622

@spike-rabbit WDYT?

In case there are toast and a full-screen modal is opened, it will be in front of the toasts until another toast is displayed. I think this behaviour is actually good or at least better than what we have now (not showing the toast at all).

This would also need a v49 backport

I guess for now we don't have any choice.
What about we request a feature for the CDK the brings an alternative for the z-index base stacking.
So the cdk itself brings overlays in the correct order? Something like a priority config or so.

since the z-index based stacking is our own (disgusting) hack, from a CDK POV there's no change in using popover. Basically stacking is always in order of opening the overlay. And with popover API it's the same. And there is now way to change stacking order with the popover API.
