Need to show something when repl is forked. #9182
Description
Describe the problem
On the site with documentation there is a greate feature, called REPL.
Everything is good except one small thing.
When you click "fork" button, nothing happens to the page except changing a link in the adress input.
It is little bit confusing when nothing happens after your action. Because all the things on a page remain the same.
Describe the proposed solution
It would be great to see some message or any other type of action which helps a user understand that a fork was succeeded.
Alternatives considered
Not sure about what I should write in this field, sorry :)
