<p>Requires Ahem font. There is a 0px size inset applied on the right float with 60px/40px top right radius.<br>
The black squares should trace the right side of the rounded rectangle's blue outline.
The second line contains a non-break space in order to avoid rounding/painting problems in the test.</p>
