Update chat layout in current call with the chat open if the setting is updated

Related to #571 (closed).

1. Make a call
2. Click on the Chat button to open the chatview
3. Click Open Settings > General > Change Layout (under the Chatview section) to the other option, i.e. Horizontal view/Vertical view
4. Click Close settings
5. The call has not updated the chatview as the chatview is in the previous setting
6. Workaround: close and open the chatview but clicking on the Chat button twice

If there is a current call with the chatview open and the setting is updated, can the position of the chatview in the current call please be updated without the workaround?

What do you think?

Thank you
