Expected Behavior

receiving event.detail with the data send.

Current Behavior

if the data is an array, the event.detail is not correctly setted.

Steps to Reproduce

From a client send a vendor request in obs to the vendor (with CallVendorRequest to vendorName obs-browser) with data as array or object (in js type) and you have the reproduction.

In the log, we can see the message I have send.

In one the event_data is

 {
  "Henry": {
    "is_chat": true,
    "point": 4,
    "pseudo": "Henry"
  },
  "Wally": {
    "is_chat": false,
    "point": 0,
    "pseudo": "Wally"
  }
}

this succeed with event.detail containing the information.

[
  {
    "is_chat": true,
    "point": 4,
    "pseudo": "Henry"
  },
  {
    "is_chat": false,
    "point": 0,
    "pseudo": "Wally"
  }
]

this fail with event.detail empty.

Anything else we should know?
