We are handling CTRL + right click on EphyWebView as special case to
ensure the context menu is shown. This probably worked with WebKit1,
because the context menu was handled by the EphyWindow on button press
event, but now it's preventing the WebKitWebView from handling the
event. Since the EphyWindow no longer handles the button press event,
it ends up being handled by the EphyNotebook that shows the tabs popup
menu.
