Mathjax texfiltercompatibility option does not work with $$

1. Enable MathJax filter. Set all settings to default. 2. Create page resource. Insert some text with equations. Example1: $$a$$ and $$2b$$ and [x] and [2y] 3. Preview page, and see, that each equation is placed on new line. 4. Enable texfiltercompatibility in mathjax settings. 5. See, that there are problems with equations in $$, while [] equations are inline, as expected. 6. Apply patch. 7. Check that all equations are inline. 8. Check than <tex> and [tex] tags also works as expected. Example2 (insert in HTML editor): <p>$$a$$ and $$2b$$ and [x] and [2y] and <tex>\alpha</tex> and <tex>2\beta</tex> and [tex] \Sigma [/tex] and [tex] 2\Omega [/tex] </p>
