Are you sure handled events here are all "default"?  I guess in the general
plugin case (not browser plugin) there's no real distinction between default vs.
script, right?  Browser plugin definitely has that distinction but presumably we
don't hit this code path for webview (wjmaclean@ is the expert).

I didn't want to change the pepper API because I didn't think it made sense to
propagate this any further into the plugin code. And since the plugin got it; I
marked it as handledDefaultHandler

I presumed webview plugins went via
components/plugins/renderer/webview_plugin.cc which are then propagated
correctly.
