The ui-toolbar-fixed-hidden test didn't fail when I ran the tests locally. I will look into this.

The failing ui-toolbar-fixed-hidden test:

Actual: ""
Expected: "ui-toolbar-fixed-hidden"

Actual: ""
Expected: "ui-toolbar-fixed-hidden"

Further failing tests:

It will be not easy to reproduce them since we can't build anymore the master.
