There is a lot of ambiguity in this ChangeLog comment!

How about something like: (emphasis mine and can be removed)

    Change so if an element is inspected *via the Inspect Element context menu*, selected node restoration is disallowed
    until the main resource *in the main frame* changes. This way an attempt by a *sub-frame* will not change the
    highlighted element in the Main Frame's DOM tree unexpectedly.

> +    _mainResourceDidChange: function(event) {
> +        if (event.target.isMainFrame())
> +            this._restoreSelectedNodeIsAllowed = true;
> +    },

Style: Opening brace should be on its own line
Style: This function should be down at the bottom of this file in the Private section.

Can just be until a page navigation / reload.
