Comment 20 for bug 1563744

Is this the same thing reported in this forum post?
https://forum.kicad.info/t/filled-zone-cuts-corner-of-mask-on-square-pads/12009/

Or should we open a new bug for that? (That report shows that it is now easily possible to have exposed copper near pads as the copper clearance is calculated differently to the mask clearance)
