Properties Panel does not show Masks: Unable to feather or refine mask

@kattltude I might have found a work-around for this. For me at least, when I create an empty mask on a layer, as long as that mask stays empty, I am still able to edit the mask settings in the property panel. It's only when I start adding to the mask that the properties panel will break and say "no mask selected," and all the settings become grayed out. However, if I add the mask and then immediately change a setting in the properties panel to a random number, and then start adding to the mask, that somehow keeps the properties panel from breaking. I can edit the mask as normal and continue to use the properties panel settings.  Hope that works for you!
