Event Stream Tag Event Wildcards - Doesn't work with Remote Tag Provider?

Do wildcards not work in Event Streams Tag Event paths for remote tag providers? Individual tags work OK, multiple fully expanded tags work OK, but introducing a wildcard ends up not firing on any that did work with the full path. Trying to use wildcards as I'll likely end up with a couple hundred matches that I don't want to have to manually maintain when a change is made at a remote site.

Replicating the same data using MQTT Transmission and then pulling it via MQTT Engine, the same Event Stream is happy to accept the equivalent single * or double ** pattern, just using the [MQTT Engine] provider. So that kind of leads me to thinking it's a remote tag provider problem.

I can't see anything described in the docs to differentiate behaviour on provider type. And can confirm both gateways are running the current 8.3.6 Wildcards in Tag Paths | Ignition User Manual

Probably worth making a bug report.
