Yes, this is a known issue. Not all pages have been ported to use the feature yet. More have been ported to use it in Plasma 5.21, and the remaining ones will be ported in Plasma 5.22. There aren't that many left, and this is ongoing, active work, so I'm gonna close the bug as RESOLVED LATER since it's as good as done in the near future. :)
