Does this seem OK here?  It could also live in WorkspaceController or even
RootWindowController.

It doesn't look like the workspace code cares about this state at all, so I'm
inclined to move it else where. Maybe put it in RootWindowController?

+  for (size_t i = 0; i < window_->children().size(); ++i) {
+    aura::Window* child = window_->children()[i];
+    if (child->GetProperty(kImmersiveModeKey))

Shouldn't you check if the child is visible?

+      return true;
+  }
+  return false;
