There are 2 other testcases already on background-position and table-row
in 'border-collapse: separate' in the test suite.

[RC6]
http://test.csswg.org/suites/css2.1/20110323/html4/table-backgrounds-bs-row-001.htm

[nightly-unstable]

Also for CSS table:

[RC6]
http://test.csswg.org/suites/css2.1/20110323/html4/table-backgrounds-bs-row-002.htm

[nightly-unstable]
http://test.csswg.org/suites/css2.1/nightly-unstable/html4/table-backgrounds-bs-row-002.htm

Those 2 table-backgrounds-bs-row-00[1, 2] testcases are failed by IE9
and Chrome 14.0.835.186 but background-position-applies-to-004 is passed
by IE9 and Chrome 14.0.835.186. So, in my opinion, this demonstrates
that background-position-applies-to-004 is imprecise and give false
positives.

background-position-applies-to-004 should be removed because it is
duplicate or it should be redesigned. Either way, it should not remain
in the test suite as it is.
