    - open project
    - select "UIWindowBase Variant" in inspector and enter to it prefab mode
    - in RectTransform, change "middle-center" anchors to "stretch-stretch" anchors
    - we can see no RectTransform overrides in "Overrides" menu
    - exit from prefab mode to scene
    - we can see no applied "stretch-stretch" anchors in "UIWindowBase Variant" instance.

    This is very important bug, because I cannot create my new UI system based on nested prefabs.
    Please fix it.

    why not to improve it?
    This is very important in order to create flexible ui based on new prefab system
    For example
    UIWindowBase -> UICaptionWindow -> UILoginWindow (or hundreds of windows derived from UICaptionWindow)
    each has its own prefab and independent content.
    If I want change something in UICaptionWindow (base of hundreds windows) in future, I just change its prefab.
    But base prefabs UIWindowBase and UICaptionWindow has default RectTransform settings,
    and derived windows such as UILoginWindow has its own specific settings.

    I found way to fix it.

    As you can see, derived window RectTransform has different width/height.

    drawback: this settings saved only once when creating prefab variant and cannot be changed in prefab mode.

    This is not a limitation of the new system specifically. The same thing was there in the old system. The team is aware of this and has noted it down as something to look into for later releases. It won't be a trivial change so it's not something that can be implemented during this beta cycle.
