Theorically, ADE 4 supports MathML but I couldn't get the following expression (after epub3 conversion) displayed:

<math xmlns="http://www.w3.org/1998/Math/MathML">
<mrow>
	<msub>
		<mi>a</mi>
		<mn>1</mn>
	</msub>
	<mo>+</mo>
	<msub>
		<mi>a</mi>
		<mn>2</mn>
	</msub>
	<mo>+</mo>
	<mo>&ctdot;</mo>
	<mo>+</mo>
	<msub>
		<mi>a</mi>
		<mi>n</mi>
	</msub>
	<mo>=</mo>
	<mstyle displaystyle="true">
		<munderover>
			<mo>&sum;</mo>
			<mrow>
				<mi>i</mi>
				<mo>=</mo>
				<mn>1</mn>
			</mrow>
			<mi>n</mi>
		</munderover>
	</mstyle>
	<msub>
		<mi>a</mi>
		<mi>i</mi>
	</msub>
</mrow>
</math>

And should look as:



Anyone can get that result?
Regards

PS: I have IE11 (I say that because ADE 4 won't render epub3 with IE10 or lower).
