are invalid because CSS 2.1 does not define with computation rules
for tables and captions that apply to this case (at least not as far
as I know).  Therefore implementations are free to give the caption
a size such that "Filler text" must break to two lines.

Specifying a 'width' on the table caption large enough to ensure it
doesn't break lines (say, 15em) should be sufficient to make the
test valid.
