I guess that `DataTransfer::HasType()` is inlined in the opt builds and actually crashed in `EditorEventListener::DragEventHasSupportingData()` at accessing `aDragEvent->GetDataTransfer()` result without null-check because `DataTransfer::mItems` is set to `nullptr` only by the cycle collector, but it does not make sense to think that it occurs the STR in bug 1627673 comment 3. Therefore, this patch adds null-checks in `EditorEventListener::DragEventHasSupportingData()`. I have no idea how to test this with automated tests.
