My example has no emoji, wide-characters, etc. So doesn't seem related to me.

This likely occurs because the UTextAdapter.cpp code doesn't insert newlines between rows. This only becomes apparent when there's a newline at the exact end of the row because then there's no separator between the match (URL) and the remaining text.
