Facet summary reset link gets fatal error when you add a range facet to the summary

I have a facet summary with a reset link. I also have a facet with a range widget. I am building a summary processor that adds this range facet to the summary such that you can reset the entire selected range.

When you select the range facet in the summary and it is the first facet in the config then the entire summary causes a fatal error:

The website encountered an unexpected error. Please try again later.
Error: __clone method called on non-object in Drupal\facets_summary\Plugin\facets_summary\processor\ResetFacetsProcessor->build() (line 62 of modules/contrib/facets/modules/facets_summary/src/Plugin/facets_summary/processor/ResetFacetsProcessor.php).

This is caused by this piece of code in the ResetFacetsProcessor:

    // Lets use any first facet to get correct url.
    $results = reset($facets)->getResults();

    /** @var \Drupal\Core\Url $first_item_url */
    $first_item_url = reset($results)->getUrl();
    $first_item_url = clone ($first_item_url);
    $first_item_url->setOptions(['query' => $query_params]);

So it grabs the first result of the first facet. But because the first result is a result in the range it cannot get a url of this result. This again is caused by the SliderProcessor which creates Results without urls.

I'm not really sure in what place this should be fixed...
