"loading" is not working when "addCustomItem" is set to true.

[e20today]

The ActivityIndicator will trigger when the list is empty.

However, when "addCustomItem" is enabled means that the list will never be empty because whatever is searched will be added to the list automatically.

This has usability issues because it's still possible to trigger a search based on existing values, while still allowing to append new values.
Under this scenario, the users won't be aware that there's a search behind the scenes.
