[text-box-trim] Test when the line is taller than strut
As the text-box-trim trims at the specified metrics of the
line box, objects taller than that are trimmed, by overflowing
to over and under side of the line box.
This test verifies only the block-start side, but can be
extended to the block-end side when it's implemented.
