Comment 1 for bug 1490493

Analysis: The visibility of the main view radial edge button is toggled by using the connection

    Connections {
        target: Qt.inputMethod
        onVisibleChanged: nav.visible = !nav.visible
    }

If you do not close the keyboard when turning back to the main view from "Add Website" page the main view became visible before the signal onVisibleChanged is fired and when it will be fired the radial edge button becomes invisible.

Solution: Before removing the page from pageStack should be ensured that the keyboard is not visible. Maybe this could be achieved simply by adding a function call Qt.inputMethod.hide() before removing the page from pageStack.
