Write tests for implicit value calculation for ARIA positioning attributes, once testing is unblocked
Related to #2104
Track writing tests for the new browser requirements for implicitly calculating values for aria-posinset, aria-setsize, and aria-level, based on the new browser calculation requirements introduced in the ARIA PR (formerly some requirements were in Core AAM, but they were more ambiguously defined).
Suggested tests include:
- [ ] tree + treeitem -- all three attributes
- [ ] tree + treeitem, with an
aria-ownsrelationship -- all three attributes - [ ] nested comments -- all three attributes
- [ ] list + listitem
- [ ] menu + menuitem
- [ ] tablist + tab
- [ ] listbox + option
- [ ] radiogroup + radio
- [ ] table + row
@cookiecrook mentioned the tests being currently blocked by testability on the ARIA WG call.
The scope of this issue is pretty large... Most of this and more will be unblocked (and is planned to be tested) once AOM #203 or another technique makes it possible, but I'm not certain the value of keeping this particular issue open. I think it's covered by #90 and other issues. Okay to close this one @smhigley?
