Esc cannot clear selection in 4.7 editor

When I press ESC in 4.7 editor, I cannot clear selection.

Hey elementLee,

It seems actors selected in viewport can’t be deselected using escape key. This has been reported and fixed internally (UE-6390) and should be working correctly in a future release. For now, actors selected in Scene Outliner can still be deselected using Esc key. Thanks for report!
