This fixes a bug that was introduced in Select2 4.0.0 and only partially fixed in Select2 4.0.6-rc.0 where the `title` attribute that is set on the selection container (or individual selections, for a multiple select) is not cleared when the text/title of the option is not set. In most cases, users no longer see this issue because the `text` property of most data objects is set, so the `title` attribute will always be cleared correctly. There was a bug for cases where the `text` property was not set, or where the `text` property was set to an empty string, that resulted in the `title` attribute persisting with the incorrect value. We have fixed this issue by always removing the `title` attribute from the selection (or not adding it in the first place, for a multiple select) when the `text` and `title` properties of the data object are empty or not present. This also adds in a series of tests to ensure the `title` attribute is set properly in a variety of cases, building upon the ones that already existed. Fixes #3895 |

Select2
Select2 is a jQuery-based replacement for select boxes. It supports searching, remote data sets, and pagination of results.
To get started, checkout examples and documentation at https://select2.org/
Use cases
- Enhancing native selects with search.
- Enhancing native selects with a better multi-select interface.
- Loading data from JavaScript: easily load items via AJAX and have them searchable.

- Tagging: ability to add new items on the fly.
- Working with large, remote datasets: ability to partially load a dataset based on the search term.
- Paging of large datasets: easy support for loading more pages when the results are scrolled to the end.
