QMacStyle on Yosemite: QStyle::drawPrimitive(QStyle::PE_IndicatorCheckBox, ...) draws in wrong place when not active

Using QStyle::drawPrimitive with QMacStyle on Yosemite (OS X 10.10.1) with QStyle::PE_IndicatorCheckBox the checkbox is drawn at the origin instead of at the place requested by option.rect when option.state lacks QStyle::State_Active.

The attached project shows the problem. It draws three checkboxes and three rectangles to show where they should be drawn. One has State_Active turned on, and it draws in the correct place. The other two do not have State_Active turned on. One is drawn at the origin, not in the rectangle requested. The third uses a trick to work around the problem: it draws at the origin into a painter that has been translated to compensate. That one draws in the correct place.
