2E only if control has the correct role

```
<input id=test>

<label for=test>
before
<input value=value aria-labelledby=aria disabled role=presentation>
after
</label>

<div id=aria>aria-labelledby</div>
```

input with id=test should not use Step 2E (use the value of the 2nd input because it has not role=textbox due to role=presentation) but Step 2B (use aria-labelledby). It works correct in Chrome
