Notifications are not appearing in PGAdmin 4 v2.1

Running PGAdmin in server mode on Linux with Python. If I listen for a channel in a query window, and then execute a notify on that channel in another connection, there is no notification I can find in PGAdmin 4. I've verified that that the notifications are working properly by using PGAdmin III to listen on on the channel. When using PGAdmin III the notification appears in the messages tab.

Steps to reproduce:

1. Start a new query tool window, and execute: listen "foo";
2. In some other connection to the same DB execute: select pg_notify('foo', 'bar'); --I get the same behavior if using: NOTIFY 'foo', 'bar';
3. Back in the original PGAdmin 4 query tool window there is no indication of a notification arriving on that connection.
4. Still in the original PGAdmin 4 query tool window execute: select 1;
5. There is still no indication of a notification on the "foo" channel which is what was listened for in step 1
