Enable "MathML (experimental; no images)" in Special:Preferences → Apperance → Math. Then preview a page with the contents <math>a' \operatorname{a}'</math>
I expect that both prime symbols are superscripts, but the second one is too far down.
The probelem is due to an extraneous <mo></mo> MathML element between \operatorname{a} and the prime symbol. With "Client side MathJax rendering" you get <merror data-mjx-message="Wrong number of children for msup node">.

In the browser console, you see with native rendering: Invalid markup: Incorrect number of children for <msup/> tag. and the corresponding mml is
<msup> <mi data-mjx-texclass="OP" mathvariant="normal">a</mi> <mo></mo> <mo>′</mo> </msup>
in contrast mathoid generates
<msup>
<mi mathvariant="normal">a</mi>
<mo>′</mo>
</msup>To fix this we still need a test where the operator is applied to something.
If one applies a` on x one gets with mathoid
