its index was being reset for each wrapped line thus not corresponding to the actual position in the full paragraph content anymore.
basically if the emojiMask was [false, false, false, true, false] for "abc🔛d" but that text was split in two lines like:
"abc
🔛d"
then the emojiMask would be read at 0, 1, 2, then 0, 1.
now that is fixed.
it doesn't actually work since the different outputs returned are treated by LineWrapper as necessarily belonging to different lines, so we'll have to do something different.
