Thanks for all your anwsers. In what I did for Firefox, the notations overlap so
I agree with this option. However, as Bruce indicated, some combinations are not
clear: for instance in the MathML testsuite, there is a notation "radical
circle"[1]. What are the rules you used to establish that only a radical should
be drawn (incompatibility between notations, priority, order of values...)?
