Ability to expand the Knowledge Center when using the embedded bot (mapped to UI element)

It seems very strange to me that when using the widget, the knowledge center is expandable to provide the user with more space to view a video or article. However, if I use the embedded (mapped to UI element) option, the knowledge center is NOT expandable. 

Can the ability for the user to expand the KC bot be added to the embedded bot option?

I believe this is also what @molly.phillips was referencing in another idea post. Apologies, Molly, if I’ve misunderstood your comment.
