Please describe the bug

Webchat is connected through ASEDL to a custom bot, Websocket in the mix. Hosting is done on iOS WKWebKit.

App is running the webchat, app gets put on background, you start camera (or anything), 30 seconds later you go back to the app, connection will not be established. Send button is disabled

When webchat gets into foreground again, there'll be two new logs:

• WEB_CHAT/SET_NOTIFICATION (reconnecting)
• DIRECT_LINE/UPDATE_CONNECTION_STATUS

Connection status will be stucked at 1, connecting.

We logged Webbrowser WebSocket too:

• before leaving the window we would have 1 websocket in a readyState = 1 (OPEN) state

• returning back we see two websockets: 1) in readyState = 1 (OPEN) state, 2) in readyState = 3 (CLOSED) state
