ProjectQuery doesn't obey multiple sort orders
While the new/edit
ProjectQuery form supports setting a secondary and tertiary sort clause, these project custom query settings are not obeyed when rendering the projects index view as a list.
The above is equally true for non-persistent
ProjectQuery sorting. In contrast to
IssueQuery, when sorting by a column is requested (by clicking the column header), the previous sort clause isn't preserved and re-used.
Behavior is observed on Redmine trunk at r21194.
I haven't looked into this and I'm not certain if it's a defect or a not-yet implemented feature.
