What is the purpose of $form_state->setRebuild(); in the example code?

It may not be bug. When you refresh or reload page it will build form again. So form state will reinitialize.

@cilefen I think it is not bug. It normal to reinitialize of variable on refresh. So no need for any code. But if @xandeadx needs to retain value then he may store value in session.

On F5 button form submitted, not just "refreshed". Browser send previous POST request.

If you don't like case with F5, another example — user click button twice, using "back" in browser, and click third time to button.
