Message:

Ensure that a user can publish_posts before making a post sticky.
Props: danielbachhuber, whyisjake, peterwilson, xknown.
Prevent stored XSS through wp_targeted_link_rel().
Props: vortfu, whyisjake, peterwilsoncc, xknown, SergeyBiryukov, flaviozavan.
Update wp_kses_bad_protocol() to recognize : on uri attributes,
wp_kses_bad_protocol() makes sure to validate that uri attributes don't contain invalid/or not allowed protocols. While this works fine in most cases, there's a risk that by using the colon html5 named entity, one is able to bypass this function.
Brings r46895 to the 5.3 branch.
Props: xknown, nickdaugherty, peterwilsoncc.
Prevent stored XSS in the block editor.
Brings r46896 to the 5.3 branch.
Prevent escaped unicode characters become unescaped in unsafe HTML during JSON decoding.
Props: aduth, epiqueras.
