When the path returned by NodePath.get() is passed back to plugins code, we must make sure to always initialize the context (otherwise it re-uses a possibly wrong cached contex).

I'm marking this PR as i: regression even if this bug was already present, because #12331 made it more common (noScope: true was almost ignored before that PR, while after that PR it's respected).
