Checked QTooButton background can't be changed when using Windows 11 style

When using a checkeable QAction in a QToolBar on Windows with the new Windows 11 style QToolButton doesn't offer any visual feedback other than the icon being depressed. I don't know if this is by desing. I tried to change the background color using css, but it doesn't work. The same exact code is able to modify the background color in Qt 6.3 or if I force a different style (e.g. QApplication::setStyle("fusion") )

toolbar->setStyleSheet(
    "QToolBar {border: none;}"
    "QToolButton:checked {background-color: #ff0000;}"  // Change background color when checked
);

Checked action (top) vs unchecked (bottom):
