Hey #a11y folks, suppose I have a form with a button that opens a mini-form in a popover or dialog. Does it make sense to stick things like `aria-required` or `aria-invalid` on that button if things in the mini-form are required / invalid?
On one hand, this feels semantically wrong? The button itself is just a trigger and can't really be "invalid" in anyway. On the other, since the actual invalid elements are in the popover or dialog, there's no other indication of this state (apart from manual descriptions).
