Previously the slider path length would be snapped using the current beat snap setting on *every* change of the slider path. As it turns out this is unexpected behaviour in some situations (e.g. when reversing a path, which is expected to preserve the previous duration, even though the slider may be technically "unsnapped" at that point in time due to a different beat snap setting being selected afterwards).
