ADDITIONAL SYSTEM INFORMATION :
The JDK version where the issue started appearing/occurring
JDK 26, JDK, 25.0.1
javafx 26-ea+14


A DESCRIPTION OF THE PROBLEM :
Detailed explanation of the problem, including any error messages
The context menu remains open even after the node that owns the menu is no longer in the scene.
The bug only occurs when using the macOS system menu item, which hides the node the ContextMenu belongs to, then the ContextMenu is still visible.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
A clear set of steps to reproduce the issue/reproducible test case
Start the attached ContextMenuApp on macOS. Right click on "View one: right click for context menu" and while the ContextMenu is shown, click on system menu "View / View two".

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The shown ContextMenu should be hidden.
ACTUAL -
The ContextMenu is still visible but the node it belongs to is no longer there. If the user now uses the ContextMenuItem it will lead to exceptions as the underling node it belongs to is not present in the scene anymore.
