Fix layout-padding css

Adds a `,` which was missing in 5caa22b2c444485b3d340cda662d8808b1fc381d when `layout-padding` was readded. Also removes a comment saying `layout-padding` is depreciated since it has been readded.
I don't think this line belongs here anymore. I should probably be removed.
(Not sure if we need a similar rule for `padding-top` though.)
