I don't know the webkit code, but here are some comments.

Be sure to consider all the elements that can be embellished operators:

Some reftests for embellished op (I think Webkit supports reftest?):

In Mozilla, instead of using functions, we store pointers on the MathML frames (pointing to the core frame). Actually, we store a structure with such a pointer and other info relevant to operator stretching. I don't know why that was done that way, but the stretchy data may depend on several elements/attributes in the MathML tree, so it may be expensive to have to compute them if they are used several times. I don't know what is the best for Webkit.
