Below is a screenshot from `UnrealEngine\Engine\Source\Runtime\Engine\Private\EdGraph\EdGraphSchema.cpp`

Why is `WITH_EDITOR` used at all in this file? My understanding of the code in `EdGraph` is that it is only relevant to editor builds that use graphs. I would assume that `WITH_EDITOR` should apply everywhere. But it is used selectively in this file, which makes me think that I don’t understand the macro very well. Can someone explain?
