<Swing Dev> RFR: 8254112: javax/swing/plaf/basic/BasicComboPopup/JComboBoxPopupLocation/JComboBoxPopupLocation.java fails on windows

[Prasanta Sadhukhan]

Please review a test issue where the test was seen to be failing on windows mach5 system in hidpi mode.
I have ran the test locally with different scale factors without reproducing the issue. Also, mach5 job running this
test for several iterations works ok. So, proposing to remove the test from ProblemList.
