Fix ASSERT in ListMarkerPainter::paint

Fix ASSERT in ListMarkerPainter::paint

The original ASSERT checked against capacity
but StringBuffer can decide to increase that
to 16 when appending characters, which happens
in the testcase. Instead test that the
reversed length equals the original length.

PTAL. I guess removing the ASSERT is also an option.
