PR286001
Since we traverse through text by visual lines instead of blocks, word wrapping causes some
bad behavior. Changing the way we traverse text to jump by words instead of lines. This will
mean it takes longer to finish spellchecking, but the removal of any loops allows webkit
processing to continue. This gives priority to user actions while still completing a large
paragraph in a reasonable amount of time.
