[nightly-unstable] 2 problems with font-size-114 : font-size of span redefined, too many levels or "may" flag missing

Hello,


http://test.csswg.org/suites/css2.1/nightly-unstable/html4/font-size-114.htm

1-

line    12     span { font-size: larger; }

    13     .tests * { vertical-align: bottom; }

line    14     .tests, span { font: 900 1em Ahem, Verdana, sans-serif;
color: navy; }

At line 12, font-size of inner spans is set and defined to be 'larger'.
At line 14, font-size of spans is reset and redefined to be 1em which is
the font-size of its parent. The font shorthand redefines the font-size
at line 14. So, current browsers (Firefox 10, Opera 11.61, Chrome
17.0.963.46) are correctly handling such test.

Line 14 should be instead/rather/replaced with:

.tests { font: 900 1em Ahem, Verdana, sans-serif; color: navy; }

span {font-family: Ahem, Verdana, sans-serif;}

The specification says:
"
A <relative-size> keyword is interpreted relative to the table of font
sizes and the font size of the parent element. Possible values are: [
larger | smaller ]. For example, if the parent element has a font size
of 'medium', a value of 'larger' will make the font size of the current
element be 'large'. (...) The UA *may* have to extrapolate table values
if the numerical value goes beyond the keywords.
"

and the table of font sizes is:

CSS absolute-size values
xx-small  x-small  small  medium  large  x-large  xx-large

So, a test which would test all known absolute-size would only use 6
levels deep of nested-ness (depth of tree). In font-size-114, there are
25 (!) levels of nested spans. So, either the test should use the "may"
flag or it should reduce the levels of nested spans to 6 levels.
