2. Set dynamically mathbackground attribute to <mo>
(see the attached testcase)
<math>
<mstyle displaystyle="true">

<mi>X</mi>
<mo>+</mo>
<mfrac>
<mrow>
<mi>X</mi>
</mrow>
<mrow>
<mi>X</mi>
</mrow>
</mfrac>
</mrow>
<mrow>
<mi>X</mi>
</mrow>
</mfrac>
</mstyle>
</math>

Setting mathbackground to any other element in this code does not cause the problem.

Thanks for the report. That seems to be yet another issue due to mstyle.
Perhaps mapping displaystyle to a CSS property would help here. In general I wrote https://wiki.mozilla.org/MathML:mstyle and suggested the MathML REC to actually keep only a few relevant attributes. displaystyle is one of them.
