Dev Tool Ouput

Opening a websocket connection using IOS (tested with 8.1, but I suspect the issue is there for all version) after going offline (Plane mode off/on) cause Safari to crash with

WebSocket connection to 'ws://10.0.1.12:8080/chat?X-Atmosphere-tracking-id=c884a896-1944-4793-b2ed-6563e218f407&X-Atmosphere-Framework=2.2.6-javascript&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&Content-Type=application/json&X-atmo-protocol=true' failed: Invalid UTF-8 sequence in header value

Before going offline, the same URL just works:

Using URL: ws://10.0.1.12:8080/chat?X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.2.6-javascript&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&Content-Type=application/json&X-atmo-protocol=true
atmosphere.js:3171

The issue seems to be with the length of the query String. For example, doing 

ws://10.0.1.12:8080/chat?X-Atmosphere-tracking-id=0

will works. But doing

ws://10.0.1.12:8080/chat?X-Atmosphere-tracking-id=0dsdasdasdasdsa

won't.

Attached is the Safari Dev Console output. This can be easily tested using the console.
