A multiple select box with CloseOnSelect: false jumps to top of dropdown list

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate
• The issue still exists against the latest master branch of Select2
• This is not a usage question (Those should be directed to the community)
• I have attempted to find the simplest possible steps to reproduce the issue
• I have included a failing test as a pull request (Optional)

Steps to reproduce the issue

1. Have a multiple select box
2. Have closeOnSelect set to false
3. Scroll down and select something
4. You will jump to the top of the dropdown list

Expected behavior and actual behavior

When I follow those steps, I see... a jump to the top of the dropdown list

I was expecting... not to jump to the top of the dropdown list, so that I can continue to select more items at the same point in my long dropdown list

Actually I'm gonna answer that for you. No, because there is already an issue about this at #4417.
