…ecification The legacy alignment presentation hints differed from the specification in a way that was breaking them when dealing with `<img>`. The culprit seems to be the selector `img[type = image i]` which seems a little nonsensical. This change makes the CSS in `presentational-hints.css` match what is found in the specification. There is still an issue with "bottom" alignment of replaced elements and more investigation is necessary to understand what specified or unspecified behavior we are failing to implement.
