after discussion on #webkitgtk+ and #python on irc.gnome.org, i tried
to rebuild webkit to check the error reported by g-ir-scanner, and
found this:

DerivedSources/webkit/WebKitDOMEventTarget.h:62: Warning: WebKit:
webkit_dom_event_target_add_event_listener: argument handler: Missing
(scope)
annotation for callback without GDestroyNotify (valid: call, async)
DerivedSources/webkit/WebKitDOMEventTarget.h:68: Warning: WebKit:
webkit_dom_event_target_remove_event_listener: argument handler:
Missing (scope)
annotation for callback without GDestroyNotify (valid: call, async)

... there are other errors that cause different method to be marked
`introspection=0`, but this looks to be the reason
add/remove_event_listener are failing.
