After performing a regular drag and drop gesture in the primary stage, if a dialog is displayed immediately, its buttons can't be clicked.

To reproduce:
- Run the attached test on Linux, with any recent JavaFX version (20 to head, also 17.0.10)
- Drag the blue rectangle and drop it into the red one
- Press the X button to close the stage, a dialog shows up (see attached picture Dialog.png)
- Try to click the Cancel/OK buttons, it won't be possible, unexpectedly.
- Press the X button of the dialog to close it and exit

Expected results:
- The Cancel/OK buttons are clickable

Actual results:
- The Cancel/OK buttons are not clickable

Workaround:
- There is no workaround, other than using any version of JavaFX lower than 20-ea+14, or lower than 17.0.10

Bisecting the JavaFX versions that work and fail leads to the commit that causes this issue: The fix for https://bugs.openjdk.org/browse/JDK-8292922 that was added in 20-ea+14, and also backported to 17.0.10.
