I'm not surprised.  Newlines in the buffer serve as anchors for the
display engine when it moves non-linearly, e.g. goes back by N lines.
Handling the case where a newline does not indicate a beginning of a
new screen line is painful and tricky.

Well, at least with R2L users can turn off the reordering if it
happens to screw them up too badly.
