Swarup Ukil 4e99e4a115 Bug 2024341 - Ensure pseudo-elements that use attr() recascade when their originating element's attribute changes. r=emilio,firefox-style-system-reviewers,layout-reviewers
As it stood, if the originating element did not use attr(data) while
its pseudo-elements did use attr(data), then if data's value changed,
we would miss recascading the pseudo and leave them stale.

This patch only covers some pseudo-elements: generated content pseudo
elements (::marker, ::after, ::marker, ::backdrop), ::first-letter and
::first-line, and UA widget pseudos.

More work is needed for the remaining pseudos: Bug 2037724
