Fix of "Support on build plate only" no longer overridden by support painting (#6863) This is a regression to a late PrusaSlicer 2.4.0-alpha0 change 	8dfc0422a878c5e44d4233c6ce522c77a0c3280f     Faster and hopefully more reliable projection of paint-on support     blockers and enforcers on a sliced mesh.     Previous d89f01c71795e324f510939e2cece05b9586291c did not fix it.
