Is there a reason why you want this to be flexible? CRWContextMenuController
could work with UIWebView, but I don't think we would need that. Do you want to
make CRWContextMenuController directly dependent on WKWebView to keep things
simple?

[Olivier, 2017/01/13 10:20:25]

I made this to depend directly on WKWebWebView.
I let the javascript delegate as webcontroller adds some checks on it.
I am not sure it is needed as we only call simple commands here, but I did not
want to drop the check silently.
