ColorDialog: The text fields on ColorInputs.qml are buggy for the Fusion, Imagine and Universal styles.

The Fusion style and the Universal style behave similarly, in that the text fields for rgb, hsv and hsl are all shrinked for the first time they're shown.
 
But if the user closes and reopens the dialog, it will display the text fields correctly.

The Imagine style, suffers from a similar issue, but with the Imagine style, it doesn't help to close and reopen the dialog. For some reason, the row layout for the text fields are sharing an equal amount of space with the ComboBox for selecting color system, which is also undesirable, and unique to the Imagine style.
