deno.jsonc "unstable" format?

I added this entry to my deno.jsonc:

"unstable": [
  "broadcast-channel",
  "ffi",
  "fs",
  "kv",
  "net",
  "http",
  "worker-options",
  "cron"
],

"unstable": [
  "broadcast-channel",
  "ffi",
  "fs",
  "kv",
  "net",
  "http",
  "worker-options",
  "cron"
],

…and stopped passing --unstable to the CLI, but now I'm getting errors:

error: ReferenceError: BroadcastChannel is not defined

error: ReferenceError: BroadcastChannel is not defined

What's the proper syntax? The schema only has:

"unstable": {
  "type": "array",
  "description": "List of unstable features to enable.",
  "items": {
    "type": "string"
  }
}

"unstable": {
  "type": "array",
  "description": "List of unstable features to enable.",
  "items": {
    "type": "string"
  }
}

…and I couldn't figure what the values are expected to be from reading the source code either. The feature name is correct (see screenshot), but that doesn't seem to work.

@bartlomieju is that a bug? This should work acording to the code I'm reading in the feature checker right now. Oh wow even --unstable-broadcast-channel passed to the CLI doesn't work 😮 Well, I'll just revert to passing --unstable everywhere then…

@bartlomieju @crowlKats I think I fixed https://github.com/denoland/deno/pull/21466, if you have time to review it
