Can |manager| be null?

[Andre, 2015/03/02 22:45:38]

For these FromWebContents kinds, it seems like it's pretty common practice to
assume non-null (set up by TabHelpers).
It might be null if a test does not set it up.

[Robert Sesek, 2015/03/02 22:50:22]

OK. The popup manager on the LHS was null-checked, which is why I asked.

+  scoped_ptr<SingleWebContentsDialogManagerCocoa> native_manager(
+      new SingleWebContentsDialogManagerCocoa(this, sheet, manager));
+  manager->ShowDialogWithManager([sheet sheetWindow], native_manager.Pass());
