<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. -->
