Why not just include LayoutTests/resources/gc.js?

Maybe use const?

> LayoutTests/editing/selection/expando.html:23
> +    var count = 0;

Maybe use let?

Ditto.

> LayoutTests/editing/selection/expando.html:41
> +    var count = 0;

Ditto.

> LayoutTests/editing/selection/expando.html:44
> +        getSelection().setBaseAndExtent(document, 0, document, 1);
> +        getSelection().getRangeAt(0).expando = 1;

I think another scenario we should consider is modifying selection after this.
