<p>Tests hidden node name computation as part of the <a href="https://w3c.github.io/accname/#comp_labelledby">#comp_labelledby</a> portion of the AccName <em>Name Computation</em> algorithm.</p>
<!--
These tests verify browser conformance with the following note as part of accName computation Step 2B:
"The result of LabelledBy Recursion in combination with Hidden Not Referenced means
that user agents MUST include all nodes in the subtree as part of
the accessible name or accessible description, when the node referenced
by aria-labelledby or aria-describedby is hidden."
-->
