MathJax not working on Cloze questions under some circumstances

MathJax will not render math if this math is inside an itemized list of a cloze question, and there's no math outside the list.

Please see attached image. I've created a quiz with 4 questions containing basically the same text:

• 1st one is a description question, with text containing embedded math
• 2nd one is the malfunctioning cloze question. It has only an itemized list with 2 items, and the second one has an equation. The equation is not rendered.
• 3rd question is the same as above, but with a text-only paragraph before the list. Same behaviour, even changing the itemized list into a enumerated one.
• 4th question: Same as 2nd, but embedding an equation into the first paragraph's text. Now the two equations are correctly rendered.

My system:
Test Quiz Filter settings are as follows:
TeX notation OFF (1st place)
MathJax ON (2nd place)

The question text of the malfunctioning cloze question is (in HTML format):
—
<ul><li>The <b>audio band frequency range </b>is:

.</li><li>The<b> capacitor's AC impedance</b> is: ( Z_C(j\omega )= )

.</li></ul>
