The ability for Web authors to make dynamic pages is important and was requested by many users. In the case of MathML it allows such things as writing interactive pages, i.e. math quiz or similar. For the simplest interactions, the MathML specification provides the ''maction'' element, which is partially implemented in Mozilla's MathML engine. | The ability for Web authors to make dynamic pages is important and was requested by many users.

However, Mozilla's | However, Mozilla's maction implementation has several bugs/spec violations and some features asked by users such as the ''tooltip actiontype'' are not still implemented. Similarly, the rendering of MathML formulas created by Javascript is not always updated correctly. This is problematic, for example to render the MathML code generated by the MathJax library. | ||
This project consists of several parts. Firstly, I intend to develop a full maction support (for example, implementing the tooltip actiontype) and to fix known maction bugs. I intend to write tests for maction and dynamic MathML rendering in general to reveal previously unknown bugs and make the implementation more reliable. Also Mozilla MathML demo pages are incomplete and out of date, so I want to update them to follow our current maction implementation and using MathML syntax instead of HTML+CSS. | |||
Finally, there are some things in MathML REC that are not clear or cases when Mozilla implementation differs from the REC, e.g. [https://bugzilla.mozilla.org/show_bug.cgi?id=749044 bug 749044]. During this summer I plan to discuss these issues with MathML WG, fix them in Mozilla MathML implementation and possibly implement more features from the MathML spec. | |||
