SIA-R57 is potentially not recognizing the search landmark

[offsetChris]

I came across an instance where it seems like the search landmark is not being recognized by the check, however this may need further investigation. The search landmark should not require an accessible name unless there are multiple in the same document. The code example may shed light on this issue:

<form role="search">
  <label>
    Search
    <input type="text">
  </label>
  <button type="submit">Search</button>
</form>

🤔
<form> without an accessible name do not have an implicit role (per HTML AAM), which we cannot really handle in the Accessibility tree building the way we currently do it (#298), so we hack around a bit in the rules that need it, such as R57. However, this hack should accept the explicit role.

I guess there is some problem in hasIncorrectRoleWithoutName…

@offsetChris When trying to run R57 on that example, I get no error 🤔

const form = (
  <form role="search">
    <label>
      Search
      <input type="text" />
    </label>
    <button type="submit">Search</button>
  </form>
);

const document = h.document([form]);

main();

async function main() {
  const result = Array.from(
    await evaluate(Rules.get("R57").getUnsafe(), { document })
  );
  const failed = result.filter((outcome) => outcome.outcome === "failed");

  console.log(`failures: ${failed.length}`);
}

Gives me 0 failures.
Do you have a page to reproduce the problem? Could it be due to an older Alfa version?
