Code review comment for lp:~tpeeters/ubuntu-ui-toolkit/NewColors

Autolanding fails:
 Test Result (2 failures / ±0)
ubuntuuitoolkit.tests.gallery.test_gallery.GalleryAppTestCase.test_progress_and_activity
ubuntuuitoolkit.tests.gallery.test_gallery.OpenPagesTestCase.test_open_page(progressBars)

I don't get those failures locally when running only those tests
