I misunderstood the traditional behavior before bug 1789967, that is, `HTMLEditor` collapsed `Selection` to end of the deepest last child container element **or text node** of the `<body>`, rather than to end of **only** the deepest last child container element. This misunderstanding caused the backout of the first landing, but I didn't realize this mistake. Therefore, this patch makes the crashtests which are touched in bug 1789967 and the collapsed point is at a text node (or failed to consider the collapsed point) collapse `Selection` to end of the deepest last text node of their `<body>` elements.
