QCheckBox used as editor in delegate does not display checkmark when using Windows11 style and no text

When using QCheckBox as an editor widget in a delegate (e.g., QStyledItemDelegate::createEditor), the checkbox does not display its checkmark indicator when:

• The active style is windows11
• The widget is visible, has non-zero geometry, and isChecked() returns true

Under these conditions, the checkbox appears blank, even though it is present and functional.

When switching to the Fusion style, the checkbox displays correctly.
