0027865: Invalid face selection for MultipleConnectedInteractive with exteranal setted display mode.
If face of AIS_MultipleConnectedInteractive has been selected, the wireframe of object will be displayd. It's reproduced when diplay mode of AIS_InteractiveContext has been setted to Wireframe, but object's display mode is shading.
The root cause of such behavior is displaying AIS_ConnectedInteractive stored by AIS_MultipleConnectedInteractive.

void AIS_InteractiveContext::SetSelected (const Handle(SelectMgr_EntityOwner)& theOwner, const Standard_Boolean theToUpdateViewer)
  // some code

  if (!myObjects.IsBound (anObject))
    Display (anObject, Standard_False);

  // some code

This code seems usefull if selected object is not displayed, but is it possible?

It work "correctly" (visually) if "real" AIS_IO's display mode equal context display mode only.

See also AIS_InteractiveContext::GetDefModes, which return context display mode instead of real display mode.
