Why this matters: Screen reader users rely on accurate role semantics; unsupported ARIA attributes create confusion about element purpose and can cause assistive technologies to misinterpret or ignore the element entirely.

Before

<a class="ytmVideoInfoVideoTitle" aria-level="2" href="https://www.youtube.com/watch?v=iWO5N3n1DXU">
  <span class="ytAttributedStringHost ytmVideoInfoLink ytAttributedStringWhiteSpaceNoWrap">Web Accessibility Perspectives: Video Captions</span>
</a>

After

<a class="ytmVideoInfoVideoTitle" href="https://www.youtube.com/watch?v=iWO5N3n1DXU">
  <span class="ytAttributedStringHost ytmVideoInfoLink ytAttributedStringWhiteSpaceNoWrap">Web Accessibility Perspectives: Video Captions</span>
</a>

Notes: The aria-level attribute is only valid on elements with heading roles (role="heading"). Since this is a link, remove the unsupported attribute entirely. If heading semantics are needed, use a native <h2> element instead; if this must remain a link, let its implicit link role stand without modification. This addresses WCAG 4.1.2 (Name, Role, Value).
