wpt: Fix /css/CSS2/tables/anonymous-table-box-width-001.xht (#35162)

This test was failing on all browsers because before the paragraph
"Test passes if there is a filled green square and *no red*" was getting
styled with some unnecessary CSS which is not present in the reference.

Removing this CSS which is irrelevant to the actual table being tested
fixes the problem.
