Need to pass in the render_frame, and have the ErrorHelper check if it's the
main frame, an pass that down to the ErrorHelperCode (A bit weird, but that's
needed for isolation of dependencies and error logic)

[Elly Fong-Jones, 2014/03/10 19:46:51]

The NetErrorHelper already knows what RenderFrame it's observing though? Changed
the plumbing further inside NetErrorHelper, at any rate.

[mmenke, 2014/03/10 19:49:57]

Right...but this message may not be coming from the main render frame.

[Elly Fong-Jones, 2014/03/11 17:06:17]

Done.
