  <!--
    Intrinsic repeat pass: auto track resolves to 25px (from "X" at 25px Ahem),
    giving auto-fill count = 1. Track list becomes [50%, auto].
    Block size is indefinite, so 50% resolves to auto. Virtual items contribute
    to all tracks, so both tracks get 25px. Total = 50px.
    Additional pass (50% is dependent on available size): 50% of 50px = 25px,
    auto = 25px. Same result — both tracks are 25px.
  -->
  <div class="grid-lanes" style="grid-template-rows: 50% repeat(auto-fill, auto); background: yellow;">
      <div style="background: orange;">X</div>
  </div>

  <!--
    intrinsic_block_size_ preserved as 50px (pre-additional-pass,
    when 0% resolved to auto = 25px + min-content = 25px). After re-run,
    tracks = [0px, 25px], but container height stays 50px. Item in 0% track
    is 0px tall, so only yellow is visible.
