I believe this testcase is correct.

The test will show red if the padding on span.test increases the
effective line height, which is what it's trying to test. I'll
add an assertion to that effect. (A separate test would be needed
to show that the padding increases the background area.)

While line breaking is not defined in the CSS specs, the test suite
assumes that spaces provide line breaking opportunities when white-space
is 'normal'.
