As we also discussed in this bug: https://bugs.launchpad.net/ubuntu-rtm/+source/ubuntu-ui-toolkit/+bug/1517614 there are issues with the Page.head.sections that we cannot fix properly, but we released now a new PageHeader that no longer has these problems.
So from UITK I consider this fixed. The apps still need to update to use the new header.
