QtQuick: RowLayout in footer not resizing when window is maximized

Use the following main.qml in a fresh project:

import QtQuick 2.11
import QtQuick.Controls 2.4
import QtQuick.Layouts 1.3

ApplicationWindow {
    visible: true
    width: 400
    height: 600

    footer: RowLayout {
        Button {
            Layout.fillWidth: true
        }

        Button {
            Layout.fillWidth: true
        }

        Button {
            Layout.fillWidth: true
        }
    }
}

Now run and resize the window by dragging an edge or corner. You will see that the buttons nicely adjust to the size. However, if you simply maximize the window, the buttons fail to update and stay the same size as they where previously.

P.S.: Afterwards, if you change the size again once, e.g. unmaximize the window, then the buttons are the size they probably should have been when the window was maximized. It seems like when the window is maximized, a size is computed but not applied to the buttons visually, and it kind of bugs around that way. I'll be using this instead for now, which works:

RowLayout {
    width: parent.width
    anchors.bottom: parent.bottom
    Button { Layout.fillWidth: true }
    Button { Layout.fillWidth: true }
    Button { Layout.fillWidth: true }
}
