Main window does not refocus when a modal closes (DisplayServer regression)

[name-here]

Godot version:
master (cdfcf68)
From past experiences, I think this has happened with every version since multi-window support was added, but I could be wrong.

OS/device including version:
macOS Catalina

Issue description:
When temporary pop-up windows (I think they're called modals?) close, either automatically, through the user pressing the "Close"/"Cancel" button, pressing the [esc] key, or through the user pressing the OS close button (red x), the window they came from is not re-focused. This also happens when saving, which I think is because the engine pops up a window to show progress while saving, then closes it when done.

This behavior is especially annoying because you can't interact with the main window again (including keyboard input) until you click on it. So, each time you save, you have to click the main window again to re-focus it.

Steps to reproduce:
Do anything that creates a pop-up window, then close the pop-up. Options include:

• Clicking "New Project" in the Project Manager
• Clicking the plus icon in the Scene panel
• Saving a project, scene, etc.

Minimal reproduction project:
You don't even need a project to reproduce this.

Still an issue, and this should be a high priority fix because it makes using the editor on macos a real pain.
every time you press CMD + S to save a script the main window loses focus and you have to click on the window again to continue typing your code. It's awful.

See #56938 (comment).

This should be fixed by #56825, at least for the most windows. Some editor sub-windows seems to have transient parent/child relationships messed up and might still have focus issues.

if that fix is included in the Godot 4 Alpha, then it didn't work.
if the fix didn't make it into Alpha 1, then great. :D

@name-here @Byteron can you check this? Seems like an easy closed issue if it's working now.

I've not encountered this issue at all as far as I can remember, working with the 4.0 editor on macOS since the early beta versions. And I can't reproduce it on the current 4.0rc6 build. @name-here @Byteron are you still experiencing this issue?

No answer, so assuming fixed.
