## Summary
Updates the node preview rendering to use the same app context as the
main app so it can access the same plugins
## Changes
Assigns manually created vnode app context to the current instances
context
## Review Focus
This is using somewhat advanced/almost-internal Vue functionality,
however I couldn't come up with a better alternative that didn't require
recreating an entirely new app and re-registering all dependencies or
redoing how draggable node previews are done.
The draggable image needs to be rendered synchronously, so rendering a
node in the active app and capturing that isn't possible to guarantee to
be done synchronously (afaik - suggestions welcome)
