did you run bots for this? you're using a size_t elsewhere which isn't 32bits
always. either this needs to be size_t or you need to case, I think (probly the
latter)

I don't think size_t is defined in mojom files, and not too sure how to approach
this.

Another alternative would be not use size_t for index()? (unsigned maybe?)

Let me ask jamesr@.
