Bug in qt 5.15.2: Button.checkable = false is gettin ignored

[themts]

Hi guys,

I just found a bug in qt 5.15.2 which was not there on older version and is also not there in qt 6.8

When you create 2 buttons and set checkable = false, you usually could set the checked property but clicking is not changing anything.
Unfortunatley, even with checkable=false the button is changing the checked state.

    property bool t

    Button {
        x: 0
        id: button
        checkable: false
        checked : t

        onClicked: t = true
    }

    Button {
        x: 100
        id: button1
        checkable: false
        checked: !t

        onClicked: t = false
    }

Is there any workaround to get the correct behaviour back?
Of course I know about ButtonGroups, but that is not what I'm looking for.

Checkable and checked are not components of Button QML.

A similar question here; https://forum.qt.io/topic/36479/solved-button-checkable-and-checked-not-working albeit a different answer/outcome from my response. Regardless, I still myself, cannot use checkable or checked with Button.
