Separate fixed positioning of mask and contents
I have a situation where I want a mask to reveal its fixed-position contents, but I don't appear to be able to do that. I don't see any reason that the mask and its contents should be inherently related, even if you want to set it that way by default (when the mask is attached) - I should be able to select either of them and select/deselect the "Fix position when scrolling" toggle.
It's frustrating how essential features for prototyping are not included, adobe makes it very difficult to build anything in XD past the basics.
Yeah some of these things are so annoying with Adobe
+1 I have this same issue.
