Is it OK to add a field to ContextMenuParams that is not directly represented in
blink::WebContextMenuData? Or should I commit to Webkit first?

[Mike West, 2015/05/19 10:11:22]

I'd suggest adding the logic to Blink first (you'll want to look at something
around 'ContextMenuClientImpl::showContextMenu') rather than reaching down from
the embedder. If nothing else, that will allow you to use safe casting methods
that RELEASE_ASSERT if you screw things up. :)

Done in https://codereview.chromium.org/1137733004 .
