When explicitly setting an application-wide palette through QGuiApplication::setPalette, most styles won't respect the palette entries. This is because most styles override the app's palette with style-specific colors.

However, on an ApplicationPaletteChange event the qquickitems respond by inheriting the application palette, making the behavior inconsistent.

The expected behavior should be that the Qt Quick Controls styles should respect any palette roles explicitly set from the application on both startup and when the application palette changes.
