1.Latex rendering not functioning well, especially in tikzcd mode or xymatrix mode. Codes sample that were not functioning well: \xymatrix{ Y' \ar[r]^{g'} \ar[d]_{f'} & Y \ar[d]^{f} \\ X' \ar[r]^{g} & X } \tag{★}, \xymatrix{ L(g')^
\ar[r]^{1\star\eta_f} \ar[d]_{\eta_{f'}\star1} & L(g')^
\circ a\circ Rf_
\ar[d]^{\alpha} \\ a'\circ Rf'_
\circ L(g')^
\ar[r]_-{\beta} & a'\circ Lg^
\circ Rf_* }. Those provided sample codes is not rendered at all. 2. Latex code with \tag{} displays badly, making the \tag{} collapse with end of the formula after rendering.
