Original change's description:
> text-box-trim: remove inline box tests (tentatively)
>
> The specification is not updated yet, and it is not that clear to us
> which edges could be cut in these cases.
> Since we do not plan to implement the text-line-edge? property for
> now, I'd like to remove these tests to avoid confusion.
