UWP CommandBar dynamic overflow behavior not working

Question

On this page in Windows Dev Center it says

The new dynamic overflow behavior will automatically move primary commands into the SecondaryCommands area when space is limited.

But in my App there are only 4 Buttons Visible, the 5th one is not there, also not if I open the Menu, I have to put it manually into the SecondaryCommands List, to make Windows showing it.
I made a plain simple CommandBar to test it

<CommandBar>
    <AppBarButton Icon="Find" Label="test" />
    <AppBarButton Icon="Find" Label="test" />
    <AppBarButton Icon="Find" Label="test" />
    <AppBarButton Icon="Find" Label="test" />
    <AppBarButton Icon="Find" Label="test" />
</CommandBar>

Build Target and Min Version is 10.0 10586.
Also I noticed that CommandBarOverflowButtonVisibility and similar properties can't be found.

This is a feature that won't appear until the Anniversary Update--the documentation has just been updated too early. You can see the feature get explained in detail in this video from //BUILD 2016 at about 11:35. It is not currently available in Build 10586.
