Fix text wrapping bug that only happened under a specific scenario

was causing a broken string view if there was a line that had any space in it followed by a forced newline and then a line that had no spaces but was long enough to wrap. example:
A B\nThisLastLineHasNoSpacesButIsLongEnoughToWrapAnyways!!!!!!!!!!!!
