🐛 Bug Report

I'm using latest RNN version (7.25) and I'm having the following behavior:

I set right from the navigation setup the below default options:

Navigation.setDefaultOptions({
    layout : {
        componentBackgroundColor : white, 
        backgroundColor : white, 
        orientation : [portrait]
    }, 
    blurOnUnmount : true, 
    topBar : {
        animate : false, 
        hideOnScroll : false, 
        drawBehind : false, 
        background : {
            color : #FFFFFF
        }, 
        title : {
            component : {
                name : HeaderToolbar, 
                alignment : fill
            }
        }, 
        backButton : {
            visible : false
        }, 
        elevation : 0, 
        borderColor : rgba(0, 0, 0, 0.12), 
        borderHeight : 1
    }, 
    sideMenu : {

    }, 
    animations : {
        setStackRoot : {
            enabled : true
        }, 
        push : {
            enabled : true, 
            content : {
                x : {
                    from : <...>, 
                    to : <...>, 
                    duration : <...>
                }
            }
        }, 
        pop : {
            content : {
                x : {
                    from : <...>, 
                    to : <...>, 
                    duration : <...>
                }
            }
        }
    }
})

Notice the backButton: { visible: false }...

However, as soon as I push a screen into my main stack, I have a native back button showing up in the Top bar...

Why is that?
