AX: In AccessibilityObject::visibleCharacterRange, we can sometimes loop
infinitely over next-line-end positions

Based on bug reports, it seems that we can loop infinitely in
`AccessibilityObject::visibleCharacterRange()` while trying
to the `nextLineEndPosition`. It would be better if we understood why this
happened, but can't reproduce it yet, so for
now just break if `nextLineEndPosition` returns the original position. The
ASSERT should help us find a webpage where
this reproduces.
