It somehow feels like a bad idea to allow other extensions to (directly) show just any remote content in the
subPanel
.This restricts the
.url
to sources in the registering extensions origin, and allows relative URLs to be interpreted in that namespace.I am not sure how you do error reporting here. A bit more type checking and the registration or other RPC calls failing with a reported error on invalid types, would probably be a good idea in general.
Hope you don't mind the trim on the first line too much.
