Text color on QComboBox on Windows not readable when focused

Hello,

This is a regression.

On Qt 4.6.0 (rc1, and if I recall correctly also the beta) on Windows, the text color for a combobox when highlighted (combo has focus, it's background is blue) is black. Black on blue is not really readable...

The standard color for this text is white, and that's how it was up until 4.5.3.
