Hint tooltips behind window when main window always on top and subwindows not embedded

[Qubus0]

Godot version

4.0.b10

System information

MacOS 12.6.1

Issue description

When using hint tooltips while subwindows are not embedded and the main window is set to always be on top, all tooltips become virtually invisible since they stay behind the main window.

idea: embed tooltip subwindows when the main window is set to always be on top

embedded + on top

not embedded + not on top

not embedded + on top

Steps to reproduce

1. create any node with a tooltip
2. set display/window/subwindows/embed_subwindows to false
3. set display/window/size/always_on_top to true
4. hover node with tooltip

I'm having the same issue with PopupMenu when parent window is always on top, I'm thinking about a way to fix it for all Popup inherited classes, but i can't find a function that gets the parent Window when it's not embedded, all we need is make them inherit always on top when they popup, and their order should be fixed.

I have been using this for long time in a custom build with no issues, popups will always hide and return the focus to their parent window since they are transient, so what's is the issue of making them all always on top by default?

Looks like #62382, but that issue was Windows only I think.
