QTabBar background and QTabWidgets corner widget

 

Hi,
I’m trying to style the background of the QTabBar for my QTabWidget

This works fine however the background of the QTabWidgets cornerwidget is not affected.

This image shows a QTabBar I’ve styled to have a white background, and a QLabel set as the corner widget styled with a blue background.

The QTabBar is shrinking to fit the corner widget which makes sense, however I have no idea how to set the background that appears above the label. For example, trying to set a background to QTabWidget::right-corner does not work.

Any ideas?
