New Branch: Partial String Search: Dropdown results are not sorted alphabetically properly

Summary

Gitlab EE - Dropdown lists are not properly displaying results on search alphabetically.

Steps to reproduce

Go to make a new branch in EE (must have many branches to see this behavior), make a new branch, search for part of string that multiple branches would have, observe results not returned alphabetically.

Causes issue if this list is VERY long and expected result between similar names is not there, but appears elsewhere in result dropdown.

What is the current bug behavior?

Dropdown list not sorted alphabetically on partial string search.

What is the expected correct behavior?

Partial string search and dropdown results returned alphabetically properly.
