AX: WebKit's accname computation can double-include text from a node pointed
to by aria-labelledby
https://bugs.webkit.org/show_bug.cgi?id=306927
rdar://169593121
Reviewed by Joshua Hoffman.
When computing the accessible name for an element, if a child references another
element via aria-labelledby, that referenced element was being counted twice:
once when processing the aria-labelledby reference, and again when traversing
the DOM tree and encountering the element directly.
Fix this by tracking nodes that have been processed via aria-labelledby during
name computation, and skipping them when encountered again in the tree
traversal.
