AX: REGRESSION(294788@main): Voice Control/inspector report the wrong
tree-item level for a treeitem nested in a plain <ul>
https://bugs.webkit.org/show_bug.cgi?id=319267
rdar://180455904
Reviewed by Dominic Mazzoni.
294788@main (bc34242b2e93) moved hierarchicalLevel() to AXCoreObject and, in
doing
so, changed the tree-level ancestor walk from the authored ARIA role
(ariaRoleAttribute()) to the computed role(). A plain <ul> whose only child is a
role="treeitem" is demoted to a generic Group role by the list heuristic, so the
walk began counting it as a grouping level, reporting level 2 instead of 1.
Per the ARIA tree pattern, only an explicitly-authored role="group" establishes
a
grouping level. Introduce AXCoreObject::hasExplicitGroupRole() (cached on the
isolated tree) and count only those ancestors, matching the pre-294788 behavior
and other browsers.
