Facet suggest: filtering facets, choosing a value, then attempting to filter again does not work

[sandbergja]

Steps to recreate locally on the release-8.x branch:

1. Follow these steps to set up blacklight locally
2. Edit the subject facet field configuration to the following in .internal_test_app/app/controllers/catalog_controller.rb:

   config.add_facet_field 'subject_ssim', label: 'Topic', limit: 3, index_range: 'A'..'Z', suggest: true
   

3. In .internal_test_app, run bundle exec rails s
4. In your browser, go to http://localhost:3000
5. In the topic facet, click the "More >>" link
6. Type "dr" and select Japanese Drama
7. Note that the URL contains only_values=true and query_fragment=dr
8. In the topic facet, click the "More >>" link again
9. Note that the modal is not usable, with no facet values, not even an "X" to dismiss the modal! 😞

Here is what the modal looks like for me:

Removing only_values=true and query_fragment=dr from the URL fixes it for me. I believe that the links in the facet modal should not include those parameters.
