<p>Tests the <a href="https://w3c.github.io/accname/#comp_name_from_content">#comp_name_from_content</a> portions of the AccName <em>Name Computation</em> algorithm.</p>
<p>This series of tests exercises the button, heading, and link elements, because each have different characteristics worthy of testing in each of the name computation algorithm scenarios:</p>
<ul>
<li>button is a leaf node with sub-level elements presentational.</li>
<li>heading is block level, and can contain sub-level interactives like links.</li>
<li>link (a[href]) is an interactive inline element that can include non-presentational descendants.</li>
</ul>
