Web Inspector: shown() called twice on TextEditor.js

[Saam Barati]

When the inspector opens a file for the first time under the resources tab, that file's corresponding text editor (I tested on JS files), has it's shown() function called twice.

Placing a console.trace in the shown() function produces a stack trace along the lines of:

It seems like the issue is:

    prepareToShow: function()
    {
        this._restoreFromCookie();

        this.contentView.visible = true;
        this.contentView.shown();
        this.contentView.updateLayout();
    },

If _restoreFromCookie causes the content view to be shown, there is no need to do it again. Perhaps restore from cookie should return whether or not it has been shown or not.
