The fix will be available in our upcoming Volume 2 release which is scheduled to be rolled out at the mid of June, 2019. Would waiting for the official release is OK for you? Otherwise, we can provide a patch on June 3rd , 2019.
If you have any more specification replication procedure or a scenario to be tested you can add it as a comment in the portal.
