The "_placeholder" attribute is used when sending binary data, and was
incorrectly mangled (converted to a random short property, like "it",
to reduce the bundle size).
This bug was introduced in [1], included in `socket.io-client@4.8.0`.

Debug / logging
In order to see all the client debug output, run the following command on the browser console – including the desired scope – and reload your app page:
localStorage.debug = '*';
And then, filter by the scopes you're interested in. See also: https://socket.io/docs/v4/logging-and-debugging/
