Comment (by cbravobernal):

 Replying to [comment:20 SergeyBiryukov]:
 > I had to revert the original commit for now due the
 WP_Theme_JSON::remove_insecure_properties() test failures, see comment:17.
 Removing those tests did not seem like the correct approach, I think they
 would need some new examples of unsafe values. Let's address that and re-
 commit the patch :)

 Happy to look at that :)
