Refine Mask only for Marquee selection
I've noticed you're unable to select a marquee around an area of a mask, and "select and mask" only that portion. I think before the properties panel, you were able to do this, through refine mask? I did launch that dialog, but it doesn't composite the refined area over new area, it simply changes the selection.
Select and mask is grayed out when there's a selection. Does this feature no longer exist? Did it ever? I tend to select portions of existing masks to revise based on clothing, or hair or skin, so I just want to focus on a portion at a time.
