Bad resource ID error when writing to BroadcastChannel

[ayame113]

When I run the code below, I get "error: Uncaught (in promise) BadResource: Bad resource ID".

const bc = new BroadcastChannel("internal_notification");
bc.postMessage("New listening connected!");
bc.close();

The data seems to be written successfully, but isn't it a bug that the error still occurs?

A workaround I found is to add a setTimeout before close.

const bc = new BroadcastChannel("internal_notification");
bc.postMessage("New listening connected!");
setTimeout(() => {
  bc.close();
}, 1000);
