Removing rule 8, makes it work as expected:

      /* rule 8 */ g > path { visibility: hidden }

Investigating soon.
Comment 2 Nikolas Zimmermann 2007-11-25 05:15:57 PST
Ok, found the culprit:
<path> is referenced by the <use> element. In our generated tree the <path> will be a direct child element of <g> (which replaces the <use> in the generated tree). Though the spec cleary states:

Rules 7 and 8: CSS selectors only apply to the formal document tree, not on the generated tree; thus, these selectors will not yield a match.

We need to support this. (while reminding ourselves that class & id selectors etc. still need to work within the generated subtree)

This needs to include landing the test case.  I think this is otherwise right, but hyatt really should have a look.
