[Reg 6.5->6.7] Menu display problem Windows 11 dark mode.

When running a Qt Widgets application on Windows 11 with the operating system visual mode set to "dark", and with the Qt Widgets application forced to light mode using

    qputenv("QT_QPA_PLATFORM", "windows:darkmode=0");

the Qt application's menu items are dark and unreadable. See attached photo.

To reproduce,

• set the Windows 11 mode to dark
• in Qt Creator
  • create a fresh Qt Widgets in Qt Creator
  • add a menu and menu item
  • then at the top of main() function, add
    • qputenv("QT_QPA_PLATFORM", "windows:darkmode=0");
  • compile and run

This menu problem is in Qt 6.7.2 but not present in Qt 6.5.5.
