QML Keys.onDeletePressed not registering

I'm trying to handle a QML/JavaScript situation where the user presses the delete key. For some reason, Keys.onDeletePressed: {} is not firing. I am getting the signal for onEscapePressed, onSpacePressed, and onReturnPressed, so I don't think it's a focus issue, or some other setup issue. I can't figure out why it's only the delete key that's not working. Is this a bug?

        Keys.onReturnPressed: {
            // code that does stuff deleted.
            console.log("Return Pressed.");
        }


        Keys.onEscapePressed: {
            // code that does stuff deleted.
            console.log("Escape pressed.");
        }


        Keys.onDeletePressed: {
            console.log("delete pressed");
        }


        Keys.onSpacePressed: {
            console.log("space pressed.");
        }

It could be you're pressing Backspace, here's a more robust check:

Keys.onPressed: (event) => {
    switch (event.key) {
    case Qt.Key_Return:
        console.log("Return Pressed.");
        break;
    case Qt.Key_Escape:
        console.log("Escape Pressed.");
        break;
    case Qt.Key_Delete:
        console.log("Delete Pressed.");
        break;
    case Qt.Key_Backspace:
        console.log("Backspace Pressed.");
        break;
    case Qt.Key_Space:
        console.log("Space Pressed.");
        break;
    default:
        console.log("Unknown key " + event.key + " pressed");
        break;
    }
}
