Describe the bug
When attempting to reconnect the connectionState remains as .connected until all retry attempts have been exhausted.

SDK Version
2.0.10

iOS Version
17.5.1

Steps to Reproduce

  1. Build the Swift example project (https://github.com/livekit-examples/swift-example).
  2. Connect two devices
  3. Simulate a bad connection on one device by enabling the 100% Loss profile in Network Link Conditioner.

Expected behavior
The connectionState changes to .reconnecting on the first reconnect attempt.

Observed behavior
The connectionState stays as .connected while the retry attempts are exhausted. The connectionState then changes to .reconnecting, and then to .disconnected.

Logs
