When creating or editing a view (under by views or global views), the Delete button under columns has no effect. I've tried with a new, unsaved view, editing a saved view, deleting default columns, deleting added columns before and after saving. In every case, the delete button appears to do nothing.

The bug is being observed in version 1.474. I have another Jenkins instance running LTS version 1.447.1 which does not exhibit this bug.
