Describe the bug

When the bot displays buttons and the user has scrolled up, upon clicking a button he needs to manually scroll down.

To Reproduce

Steps to reproduce the behavior:

1. Go to https://microsoft.github.io/BotFramework-WebChat/01.a.getting-started-full-bundle/
2. Type help
3. Scroll up and click a button.
4. The user needs to manually scroll down to see a bot reply

Expected behavior

I would expect that when the user clicks a button that the webchat would scroll to his message. After clicking a button, there is nothing to do anyways and the user wants to see the bot response.

Additional context

I have seen a number of reports in the past. For instance #1031 but I'm unsure why we would need a workaround here.
This was already implemented in #411
