Yes, it's a known problem.  The Unicode UAX#9 Bidirectional algorithm
(which is what Emacs implements for bidirectional display) does not
produce good results with LaTeX (and with other kinds of markup).

Something _should_ be done, for sure.  But for that, Someone™ should
figure out how this kind of problems could be solved using Emacs
display features.  Any solution will probably involve reordering only
parts of text, but a more detailed design suggestion is needed before
it can be implemented.  People are welcome to try to tackle this,
because I'm still busy with low-level bidi support of plain text.
