If you type

"<math>\omega</math>,"

then the MathML mode generates

<span><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML">

<mrow class="MJX-TeXAtom-ORD">

<mstyle displaystyle="true" scriptlevel="0"> <mi>ω<!-- ω --></mi> </mstyle>

</mrow>

</math></span>

<meta class="mwe-math-fallback-image-inline" style="background-image: url('/w/index.php?title=Special:MathShowImage&hash=260b57b4fdee8c5a001c09b555ccd28d&mode=5'); background-repeat: no-repeat; background-size: 100% 100%; vertical-align: -0.167ex; height: 1.167ex; width: 1.5ex;" aria-hidden="true"></span> ,

and an undesired space is added between the math expression and the comma.
