<meta name="assert" content="The height of an inline-level box whose line-height is normal and which only uses glyphs from the fallback font
                             must still take the strut from the first available font into account.">
<style>
@font-face {
  font-family: 'high-a-only';
  font-style: normal;
  font-weight: 400;
  src:  url(/fonts/Revalia.woff) format('woff');
  unicode-range: U+0061, U+0020;
}
@font-face {
  font-family: 'deep-b-only';

div {
  position: absolute;
  line-height: normal;
  font-size: 100px;
  color: transparent;
  border: solid black 1px;
}

.h { font-family: high-a-only; }
.dh { font-family: deep-b-only, high-a-only; }
</style>

<p>There should be two stacked rectangles below: a tall one above a short one, both the same width, sharing the edge at which they touch.

<!-- Both divs show the same content with the same font,
     but the first div has an unused first available font
     while the second one does not.
     As the height calculation takes the strut into account,
     these two boxes should have different heights -->
<div class="dh">a</div>
<div class="h">a</div>
