Fix wpt test for css-generated text on inline element

The wpt test for css-generated text on inline elements
was failing since the reported LCP was being triggered
for the next block-level ancestor as outlined in the
spec.

Fixed the test to account for the aggregation of LCP
entries at the next block-level ancestor.

Also prevent the test from timing out if no LCP entries
are found.
