INTERNAL_AllowDisableClickTransparency

This boolean determines whether the popup can force its content to catch clicks. It will usually need to be true (for example to allow clicking on a ComboBoxItem). It should be set to false in specific cases like non-modal childWindows where we do not want the Overlay to catch and prevent all click events outside of the childWindow itself. Defaults to True.
