Odd, why is this happening on HandleKeyEvent?

       target_->OnBlur();
+    // Removal of the Textfield must be done manually here since
+    // Textfield::ViewHierarchyChanged() needs to be executed. Allowing View to
+    // do it in its destructor instead (which calls RemoveChildView()) means

     target_.reset();
     return false;
   }
