I made p static, added stability delays, and moved robot out of the EDT (as well as caught a duplicate robot instantiation). There's a merging issue that also missed adding this test to the problem list for MacOS, so it's been added here.

Getting the location just after `setVisible` on EDT may give an inaccurate result(especially if the tested system is slow, and decided to move the window somewhere else).

I suggest to wait as usual before getting the location

robot.waitForIdle();
robot.delay(500); // or FRAME_ACTIVATION_TIMEOUT
