EventQueue.getCurrentEvent() returns incorrect event

Please run the test case provided below
Note: package name is important to make it work

Click to the menu and click any MenuItem
in console you'll see "Modifiers - 0"

Now make the frame big enough to completely contain popup menu
(we need to make it lightweight)

Click to the menu and click any MenuItem
in console you'll see "Modifiers - 16"

This is the problem,
the result has to be the same for both cases

See evalutaion for more details
