EventSource could not keep alive in Edge

[yeyimilk]

EventSource: 1.0.7

1. It worked after refresh page which means that the connection can be established
2. The connection worked well if client/server keep pinging within 45 seconds
3. The connection seem broken after about 90 seconds if the client/server did not do anything
4. After about 8 minutes, it printed SCRIPT5022: No activity with 300,000 milliseconds. Reconnecting.
5. However, it still could not work after this log.

Hints: As for [email protected], It printed SCRIPT5022: No activity with 45,000 milliseconds. Reconnecting after about 90 seconds. And after this log, it can work again.

However, it could not work after the second time it printed SCRIPT5022: No activity with 45,000 milliseconds. Reconnecting
