Not a big deal, but this looks a little flaky now that the expectations have
changed subtly. Perhaps we could bypass the label altogether, something like
<label id="labelElement" for="shutdownTime">Shutdown delay: </label>
<span id="shutdownLabelBefore">Shut down computer after</span>
<input id="shutdownTime" type="text" value="10"
aria-labelledby="shutdownLabelBefore shutdownTime shutdownUnit" />
<span id="shutdownUnit">minutes</span>

Then the text content will show that the label is not involved, and this check
is just a sanity check.

Good idea.

I rewrote it to show the label is not involved without the weird role.

 
-          // There should be no title UI element.
-          shouldBe("text.deprecatedTitleUIElement() != null && text.deprecatedTitleUIElement().isValid", "false");
-          
           var labelElement = accessibilityController.accessibleElementById("labelElement");
           // This just makes sure that the label element is still visible in the AX hierarchy, even though
           // it's a label element (sometimes they are ignored).
