With my GtS account, feeds are getting updates on elk.zone, but not on canary versions.

I looked through the commits between masto 6.10.1 (used in stable release) and 6.10.4 (currently in Elk's package.json) and found the cause: commit neet/masto.js@7f01cb3, PR neet/masto.js#1255

The client no more sends an access token via Sec-WebSocket-Protocol header, but neither sends Authorization header for some reason.
