Potential issue with websockets switched off

[madsmao]

I just discovered a potential issue. I have websockets switched off on one of my production sites, and on a fairly regular basis, the site would suddenly hang. When I checked the browser console, I noticed that zones.js was spitting out 503's and 404's on trying to contact the server. Seemingly through a websocket.

Could it be, that zones.js doesn't read that websockets are turned off, and attempts to establish a socket connection anyways? That won't work for me, since I am running the production site on Cloudflare, and cannot enable websockets at this point.

Oh, and sorry for not being able to attach a dump of the errors I was getting in the console. The browser tab died on me before I was able to investigate further. Also, I have removed zones.js from the production site to see if that will solve the issue. Will report back with my findings if any.
