Adding class="no-link-warnings" to a <pre class="idl"> block suppresses warnings about unlinked or undefined IDL terms within that block.

<pre class="idl no-link-warnings">
dictionary PointerEventInit : MouseEventInit {
  long pointerId = 0;
  double width = 1;
};
</pre>

• ⚠️ Use sparingly. Suppressing link warnings can hide real issues — missing definitions, broken xrefs, or IDL that should be linked.
• The main use case is when a dictionary and interface share the same attribute names and the dictionary members intentionally don't have separate definitions (they inherit the interface member's semantics)
• Prefer writing definitions and proper xrefs over suppressing warnings
