There is no "MainFrame" when inspecting a JSContext.

I'm open to better ideas. This seemed to work okay.

Hmmm, no I think this might break split console toggling.

I think this is fine. Only concern I have is the use of this.parentSidebar.selectedSidebarPanel.show().

I am not sure this is right. Why do we need to force the sidebar to show? A comment would be good about why it is forced to show and why this uses this.parentSidebar.selectedSidebarPanel.

> Source/WebInspectorUI/UserInterface/Views/ResourceSidebarPanel.js:117
> +        this.parentSidebar.selectedSidebarPanel.show();

Ditto.

This patch still hasn't landed yet. I still don't like the patch, let me investigate some more.
