Re: [WICG/webcomponents] Selection APIs for Shadow DOM (#79)

Thanks @spocke - this is a very good point that isn't captured in the current proposal. So currently, `Selection.getRangeAt()` returns a `Range` with `startContainer` always being the left-side of the selection (even for RTL, if seems?), and `endContainer` always being the right side. I am unable to find the place in the [Selection specs](https://w3c.github.io/selection-api) where this behavior is defined, but all browsers seem to agree.

I'm wondering if the best way around this would just be to expose the [`direction`](https://w3c.github.io/selection-api/#dfn-direction) directly on the `Selection` object? That wouldn't require changing the definition of `AbstractRange`, and it would even make `getRangeAt()` a bit easier to work with, I think. Something like this:

```javascript
const selection = window.getSelection();
const range = selection.getComposedRange(); // As proposed
const dir = selection.direction; // "forwards", "backwards", or "directionless"
```

Thoughts?
