Cursor position not aligned with window coordinates

[sjschen]

Description of Issue:

Window for MCEdit-Unified shows up with buttons highlighting and tooltip appearing when the mouse cursor is well 'above' (the y-axis) of the button. It appears the y coordinate of the cursor is shifted while the x coordinate is correct. in the screenshot, the mouse cursor was actually at the top-left corner of the "Controls" button, but the highlighted button and tooltip was clearly for the "Homepage" button.

The same issue for the same version of MCEdit-Unified was reported early on 2019-July-25. However, the reporter posted it in the MCEdit2 issues page: https://github.com/mcedit/mcedit2/issues/495
