Description
### Bug explanation
I have XAML Binding Failures with MenusAndToolBars.xaml if I change the lines https://github.com/MaterialDesignInXAML/MaterialDesignInXamlToolkit/blob/master/MainDemo.Wpf/MenusAndToolBars.xaml#L355-L360 with the follwogin content:
```xaml
```
saying:
> Severity Count Data Context Binding Path Target Target Type Description File Line Project
Error 2 null (0) MenuItem.Height Double Cannot find source: RelativeSource FindAncestor, AncestorType='System.Windows.Controls.Primitives.MenuBase', AncestorLevel='1'.
Do you have an idea how to fix this issue?

Research direction
Start in MainDemo.Wpf/MenusAndToolBars.xaml at lines 355-360 and reproduce the two binding failures using the supplied ContextMenu and CompositeCollection markup. Inspect how MenuItem.Height resolves its MenuBase ancestor in this configuration. Done means the example no longer reports the Cannot find source binding errors.
