Description kipod 2013-08-07 22:57:00 UTC
in RTL wikis, when using MathJax, formulas are left-aligned.
with either TeX or PNG modes, the formulas are right-aligned on RTL wikis.

this causes completely different page rendering for users who render formulas with  MathJax, vs. users who render Math as png (or TeX, for that matter).


peace.

Is there a page / testcase where this problem can be seen?
Comment 2 kipod 2013-08-28 02:34:29 UTC
see

https://he.wikipedia.org/w/index.php?title=%D7%95%D7%99%D7%A7%D7%99%D7%A4%D7%93%D7%99%D7%94:%D7%93%D7%9C%D7%A4%D7%A7_%D7%99%D7%99%D7%A2%D7%95%D7%A5&oldid=14476142

at the bottom of the page (next to the "bug reported in bugzilla" template). note that the formula is right-aligned if you choose mathjx in preferences, and right-aligned when you choose "png" display for math formulas.

peace.

MathJax currently does not yet support RTL. In our defense, neither does any browser (for MathML).
Comment 4 Peter Krautzberger 2013-09-05 03:54:15 UTC
For future reference: http://docs.mathjax.org/en/latest/mathml.html#supported-mathml-commands. For context: MathJax converts TeX to MathML internally and then renders MathML.

i do not think this is relevant to the bug. MW software (or rather, the math extension) packages the mathJax part inside a div with style="text-align: left".  when content direction is RTL, we should change this to "right".

afaik, this should not affect the mathjax appearance - i think that this wrapper div is not part of matjax.

That seems to work correctly for me on the Math Extension master branch.

The screenshot indicates that it works.
