This clip is a bit strange. The first and last group display the way I would expect in the Editor and Print Preview (except that the slur should be closer to the beam). As for the center two groups ...
IMO, beams should ignore hidden rests. Slurs should ignore hidden rests. That said, slurs should continue to observe the position of hidden muted grace notes unless some superior method is devised to increase slur curvature.
