Mattermost DNS netpol does not allow port 5353 for Openshift

Looking at the DNS netpol here: https://repo1.dso.mil/platform-one/big-bang/apps/collaboration-tools/mattermost/-/blob/fe1f6ef0ef5c81fc23d8825536d171b0b6efbee9/chart/templates/bigbang/networkpolicies/allow-dns-egress.yaml#L16 Only port 53 is allowed. Openshift needs port 5353 for DNS lookups.

Using BB 1.11.0, Openshift 4.6.4
