[css-device-adapt] device-width, device-height dropped from spec.
Approved first-line-pseudo-016 since, by default, vertical-align
does not apply to first-line pseudo-element and because
"UAs may apply other properties as well." Therefore the may flag
makes sense. I updated also first-line-pseudo-015
accordingly.
