Really?...

The first purpose was an improvement (not a new feature).
But, after comments from @laoneo and @rdeutz it appears i did it wrong. I redid it. And now it add a fix as well due to a choices.js issue: #42774 (comment)

If it's ok with my last update of this PR, i can rebase it if required. ;)

As @Fedik mentioned already, please rebase this one to 5.1. I'm also not sure about the inline comment. Can the change be reverted when Choices-js/Choices#1110 is merged and added into Joomla?

Just rebased.

About the fix, this one could be removed when choices.js with the fix for isolated options integrated.
It won't be an issue as the fix here create an empty group to be able to display isolated options (when mixed list of optgroup and option) to be diplayed in first position.
Only with Choices library updated that it will allow to use not-in-group options to be displayed at wanted places. For now, it's impossible.

So, yes, this change could be reverted when choices fixed! ;-)
