Great analysis!

I would say that the fix is correct, but I'd wait for Andre's input.

Hear, hear. This kind of analysis should be in the code, as comment.

Do I understand correctly that this presupposes that 1) every
mathinset must have an isActive method and 2) it should return
true only if the inset has really accessible cells?

Stefan

1) You get it for free if you derive from InsetMathNest. It returns true if you have at least one cell. Any inset just derived from InsetMath, but not from InsetMathNest do not need it. 2) Yes, if you use a InsetMathNest with cells you better do not return true if you do not draw the cells.
