Topic on Project:Support desk

I would like to enhance the MediaWiki support on Wikiversity so that the following works: \begin{equation} \label{squ} \D := \vcenter{\xymatrix @=3pc {S \ar @<1ex> [r] ^{s^1} \ar @<-1ex> [r] _{t^1} \ar @<1ex> [d]^{\, t_2} \ar @<-1ex> [d]_{s_2} & H \ar[l] \ar @<1ex> [d]^{\,t} \ar @<-1ex> [d]_s \\ V \ar [u] \ar @<1ex> [r] ^s \ar @<-1ex> [r] _t & M \ar [l] \ar[u]}}, \end{equation}

The expression is put between <:math></math>.

Any help, suggestions, comments, or criticisms are welcome.

If there's something that needs to be changed on Math extension, you have to request it on Phabricator. See BUGREPORT.
