After applying this change, going to `/uiexample/view/PhabricatorAphrontBarUIExample/`,"Bars (PhabricatorAphrontBarUIExample)" renders with beautiful colors.
To see that page, enable prototypes with:
./bin/config set phabricator.show-prototypes true
Also try to create a Milestone on a Project, with the Config `maniphest.points` enabled, and try to create some Tasks with different points. Visit its Workboard to see the bar that still works with a useful tooltip.
