American Mathematical Society Research article Mathematical article with lots of {\mathbb N}^2 \times \mathbb {R} equations. Mathy McAuthorsen Institute for Advanced Webby Math Abstract

In this minimal example we explore issues with math in Lens

Titles with math are cut off at the first <inline-formula content-type="math/tex"> <tex-math>{\mathbb N}^2 \times {\mathbb R}</tex-math> </inline-formula> equation.

Titles with math are cut off at the first {\mathbb N}^2 \times {\mathbb R} equation.

Whitespace around math
Whitespace is missing {\mathbb N}^2 \times \mathbb {R} after inline equations (when appropriate) but is forced in front of an equation, e.g., in parenthesis ( f(0)=0 ), even when inappropriate.

Math in figures
See Figure 1A

Titles with math are not cut off at the first <inline-formula content-type="math/tex"> <tex-math>{\mathbb N}^2 \times {\mathbb R}.</tex-math> </inline-formula> equation.

{\mathbb N}^2 \times {\mathbb R}.

Math in references
See [ AEG0].

References to equations do not work
E.g., \begin{equation} \frac {\partial S_r}{\partial s}= L_{r-1}(f_s)+ f_s(S_1S_r-(r+1)S_{r+1})+f_s tr(T_{r-1} \overline {R}_N)+E^T_s(S_r), \tag{3}\cssId{derivata.elbert}{} \end{equation} Then refer to its ID, say ( 3).(The MathML equivalent also does not work; it's commented out below.)

Lens picks the first child of an equation element
Ideally, Lens could choose client dependent, e.g., on old or mobile browsers use fallback image. Alternatively, this could be done by MathJax but that would require coding everything into annotation-xml elements.

MathJax timinig problems
Erratically, MathJax output is tripped up. Maybe a race of Lens vs MathJax or a display:none problem
