| <p>There should be <strong>two identically sized rectangles</strong> below. |
| |
| <!-- Both divs show the same content with the same font, |
| but the first div has an unused font earlier in the list, |
| while the second one does not. |
| However, that font does not include the U+0020 character, |
| and can therefore not be the first available font. |
| If it had been, it would affect the height of the strut, |
| making the height different. |
| Since it is not, both boxes are expected to be the same height. --> |
| <div class="ba">a</div> |
| <div class="a">a</div> |
