No required entity context created using ctools_context_get_context_from_context

The function ctools_context_get_context_from_context() invokes the context creation function with the $empty parameter set to TRUE when $type is 'requiredcontext'. I wonder why that is.

I am trying to get the Panelizer preview to work on OpenAtrium and I already have applied patch #2797449 on CTools 1.12. The panelizer display contains a pane with a required entity context. When previewing, the context is empty only because ctools_context_create_entity() returns an empty context as $empty is true.

To me it seems that ctools_context_get_context_from_context() should not invoke the 'context' plugin function with $empty = true when the argument was successfully applied to the $context.

I have tested this on an installation with CTools 1.12 patched with several OpenAtrium/Panopoly patches and patch #2797449. However, the code in context.inc does not seem to differ from current 7.x-1.x so I assume my observations apply to 7.x-1.x as well.
