/**
* Custom attribute source that can override the window state.
*
* <p>This is intended for the JSON layout theme where it puts all the portlets in minimized mode to
* reduce render cost. It previously tried to set the windowState on the PortletWindow object and
* then used a flag to disable writing the window state to the DB. Because the PortletWindow is
* cached in the session, it would still break the layout for each subsequent render in that session
* though. New approach is to not modify the PortletWindow and just customize the channel XML tag
* attributes without ever updating the PortletWindow or persisting the windowState change.
*
* <p>See UP-4364
