This PR resolves the issues raised in mathjax/MathJax#3202, namely that primes are not placed properly on operators. E.g.,
\sum_n'
should act like\sum_n^\prime
but doesn't. The reason is that thePrimeItem
andBaseMethods.Prime
function don't treatmunderover
the same asmsubsup
, so this PR fixes that.This also fixes the problem with
\int\limits'
not working like\int\limits^\prime
.It also fixes the problem with
\sum''
and larger numbers of primes not using the proper size in display mode.Resolves issue mathjax/MathJax#3202.
