A DESCRIPTION OF THE PROBLEM :
There is a difference in behavior for macOS, Windows, and Linux.

Windows and Linux do not trigger the popup menu when the right mouse button is pressed and dragged from a component without a popup menu to/over/through a component with a popup menu. macOS does create a popup menu.

Please add josm-found as a label.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Run the attached test case
2) Press and hold the right mouse button down on the JLabel with the text "Right click and drag from here"
3) Move the mouse to the JLabel with the text "to here"
4) Observe that the popup menu assigned to the inner JPanel appears (macOS) or does not appear (Windows, Linux)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Consistent behavior between macOS, Windows, and Linux
ACTUAL -
macOS has different behavior from Windows and Linux
