This indicates that context is a void* in the gir, so it's unlikely any of the
binding languages can access it.
I've done quite a but of work with seed and webkit, i would suggest forget
about passing objects between webkit/gjs or even seed and expecting to interact
via method calls etc. it is unlikely to work ever.
The normal work around is to use two way messaging between the two Scopes.
Execute_script, is a method of webview afair. That allows you to send data and
call stuff in webkit scope
Then you can capture the console log, or alert messages and pass data and
events back from webkit using json.
Be aware also that webkit seems to eat memory alive when used from introspection
