User message styling lost when reconnecting to a conversation

Please view our Technical Support Guide before filing a new issue.

Version

botframework-webchat NPM package version 4.15.2 Microsoft.Bot.Connector.DirectLine .NET assembly version 3.0.2.0

Describe the bug

We have created a chatbot based on the React web chat component as per the sample 06.recomposing-ui/a.minimizable-web-chat that obtains tokens from a token service that uses the DirectLineClient from Microsoft.Bot.Connector.DirectLine to provide a token. When reconnecting the web chat UI to an existing conversation by using a token generated by passing a conversation ID to the DirectLineClient, all old messages are styled as being from the bot even if they are user messages, eg

Expected

Steps to reproduce

1. Open the web chat UI and send some messages
2. Reconnect to the conversation above using a DirectLine token generated using the same conversation ID
3. Scroll up to old user messages

Expected behavior

Historic user messages should retain the user message styling specified in the StyleSet passed to the ReactWebChat component.

@DaveM77 - Thank you for your patience. I haven’t seen the email come through. Perhaps the file size is too big? Are you able to zip the project (minus any keys/secrets) and attach it here?
