Dear Emacs Developers,

I am encountering an issue with window-absolute-pixel-position on macOS
that leads to incorrect Y-coordinate values under specific conditions. This
bug appears to manifest in two scenarios: after the system resumes from
sleep, and when Emacs is in fullscreen mode.

Environment:

Emacs Version: (30.0.50)
Operating System: macOS (After 14.00)
Issue Description:

After Sleep: When macOS resumes from sleep, the Y-coordinate value returned
by window-absolute-pixel-position is off by approximately one-fourth of the
screen height.
During Fullscreen Mode: In fullscreen mode, the Y-coordinate is incorrectly
offset by the height of the navbar.
Steps to Reproduce:

Open Emacs and position a window at a known pixel position.
Either put the system to sleep and wake it, or switch Emacs to fullscreen
mode.
Evaluate (window-absolute-pixel-position) and note the Y-coordinate.
Expected Behavior:
The function should return accurate window positions regardless of sleep
mode or fullscreen state, without any unexpected offsets.

Actual Behavior:
The Y-coordinate is inaccurately calculated, showing a significant offset
that seems to be influenced by system sleep and fullscreen transitions.

This issue can be particularly disruptive in workflows that rely on precise
window positioning, such as automated GUI testing or window management
scripts. Any insights or fixes would be greatly appreciated!

Thank you for your attention to this matter.

Best regards,
happyo
