Matter generic switch throws "Invalid event type" on short_release and other events

[hiattp]

The problem

I'm new to Matter but very eager to get some ESP32-H2 prototypes up and running. As a very basic test I've installed the latest Matter server on HA and flashed an ESP32-H2 with the generic switch example:

This commissions successfully and according to the ESP32 monitor is triggering the correct events. However, when I observe state_changed events in HA on any given button press I only see initial_press events like this (5 largely identical events per one button press in quick succession):

event_type: state_changed
data:
  entity_id: event.test_product
  old_state:
    entity_id: event.test_product
    state: "2024-05-16T16:42:32.199+00:00"
    attributes:
      event_types:
        - initial_press
      event_type: initial_press
      newPosition: 1
      device_class: button
      friendly_name: Test Product
    last_changed: "2024-05-16T16:42:32.569806+00:00"
    last_reported: "2024-05-16T16:42:32.569806+00:00"

  parent_id: null
  user_id: null

In addition to these events (which don't seem to be usable in terms of determining the actual button action/state since they appear as 5 redundant initial_press) I also see event validation errors in Core pertaining to the event types:

After a quick (and naive) code search I do see these as supported event types (see https://github.com/home-assistant/core/blob/dev/homeassistant/components/matter/event.py#L27) so it isn't clear why these are triggering errors and why I'm seeing all the redundant event notifications.

FWIW the ESP32 monitor logs for a single button press on the generic switch example is here, you can see it attempting those "short release" and "multipress complete" events:
