Limit is being ignored

Value in "How many autocomplete suggestions to show?" field is being ignored.
If you have a large number of nodes with a lot of options available in this field, it takes a very long time ( e.g. 30 + seconds) to generate the list which contains all the available values, not the number that is set in this field.

This was already discussed in another thread ( https://www.drupal.org/project/existing_values_autocomplete_widget/issue... → ), but it was related to a different version (8.x-1) of the module.
