Comment:
As per today's bug scrub:
@ramonopoly I think the first docblock of the changeset is not 100%
correct:
> Strips `style.css` attributes from all blocks in post content.
Should be:
> Strips custom CSS attributes from all blocks in post content.
What do you think?
Otherwise the rest of this changeset looks good to me.
