Hello,

http://test.csswg.org/suites/css2.1/20101027/html4/numbers-units-014.htm

http://test.csswg.org/source/contributors/microsoft/submitted/Chapter_4/numbers-units-014.htm

The testcase has been slightly updated since RC2 but nothing fundamental
changed.

Comparing an "X" of 1em by 1em with a square of 1em by 1em actually
achieves nothing in term of testing.

<meta name="assert" content="The 'em' unit is equal to the computed
value of the 'font-size' property after resolving the value 'larger'.">


If the font-size of 1em is rendered *before* resolving the value
'larger', then both black squares will have the same size.

If the font-size of 1em is rendered *after* resolving the value
'larger', then both black squares will have the same size.

The testcase does not test what it wants to test.
Since the scaling factor between medium and large is not specified
normatively by the spec, then it is not possible to compare a 'larger'
situation with a reference, regardless of code redesign of the testcase.

I think that testcase should just be removed because this 'larger'
font-size issue can not be measured, compared with a reference therefore
truly tested. I do not see how that testcase can be rehabilitated.

regards, Gérard
