below the prompt.

Could you elaborate on this? Is there a reason you would like toggling between
the tabs to reset your console selection?

No, I really want the caret to move on messagesClicked when I click underneath
the prompt, not on focus/toggling between tabs.  I find it convenient when the
console moves my cursor for me after I click.

     this._prompt.focus();
+    this._messagesElement.scrollTop = top;
   }
