Auto scroll animation issue - While refreshing the chatbot with long conversation history, the auto scroll animation keep user waiting to reach latest message

Version

Integrating the CDN version js directly on the page using script tag (No Iframe). Desktop Chrome Browser.

Issue

We have conversation retention enabled on our Virtual Agent. Hence when users refresh the VA with long conversation history, there is a evident delay(due to auto scroll animation) experienced by user to the reach latest message at the bottom.

Reproduction steps

1. Create a VA with conversation state retention enabled
2. Perform around 200+ dialogues on a single conversation
3. Refresh the page/chatbot we would see the conversations are getting restored with a scroll animation which creates delay reaching the latest message

Expected behavior

The expectation is to provide a way to block/avoid the auto scroll animation and help us stick the scroll to bottom always thereby the user can see the latest message without any delay.
