0.9.1

The sort menu's two headings were drawn as dead options. "Sort tasks" and
"Sort groups" used setDisabled, which renders a greyed-out item you cannot
pick — so the section that offers the group order read as something broken
rather than as a title over it.

They are labels now, which is the API for a heading and has been since 0.15.0.
The harness could not have caught it: its menu returned itself and drew nothing
until the check that now asserts this was written.
