    Default Window Position bug on Componen resize

    Hi together,

    If you create a window inside a container, it will be displayed correctly, even if the container size changes.

    If the window is now maximized with a maxWidth (it should not go over the entire width) then it loses its position and can no longer be moved.

    an example can be found here:

    Ext.create("Ext.container.Viewport", {
        layout: "border",
        items: [{
            region: "east",
            xtype: 'panel',
            title: 'I am Collapsible',
            collapsed: true,
            width: 200,
            height: 100,
            collapsible: true,
            split: true,
            items: []
        }, {
            region: "center",
            xtype: 'panel',
            title: 'I have a Window',
            items: [{
                xtype: 'window',
                title: 'I am the Window',
                width: 250,
                maxWidth: 400,
                height: 200,
                maximizable: true,
                autoShow: true

    1. Maximize Window
    2. Collapse/Expand right Panel
    3. Maximized Window loses Position

    Is there a quickfix for that bug available? It looks like the window is getting its old position before it was maximized.

    best regards
