MathJax.startup.getComponents() does not remove macros in Mathjax 3
Created by: jano-m
when macros are added or modified in Mathjax.config.tex.macros, then MathJax.startup.getComponents() will update MathJax to use these new macros or new definitions, however, if macros are removed from Mathjax.config.tex.macros, getComponents() will remove them from internal state and they are still applied
