HTML doesn't have a direction property, it only has @dir. On the
layout level, @dir maps to the 'direction' property for display
purposes.

Adding 'direction' to CSS in the first place was a mistake - we did it
to let arbitrary XML languages declare bidirectional content, since
XML didn't have a native @dir attribute.  HTML content should never
use 'direction' at all, and it would be ideal for SVG to define a
native direction property as well.

Just change the current @direction attribute into a semantic
attribute, rather than a display one.
