Limiting field facet with certain terms via {!terms} not taking into account sorting

When I'm doing limiting facet keys with {!terms} it doesn't take into account sorting.

First query not limiting the facet keys:

facet.field=title&facet.sort=count&facet=on&q=:

Response as expected:

"facet_counts":{ "facet_queries":{}, "facet_fields":{ "title":[ "book2",3, "book1",2, "book3",1]}, "facet_ranges":{}, "facet_intervals":{}, "facet_heatmaps":}}

When doing it with limiting:

facet.field={!terms=Book3,Book2,Book1}title&facet.sort=count&facet=on&q=:

I'm getting the exact order of how I list terms:

"facet_counts":{ "facet_queries":{}, "facet_fields":{ "title":[ "Book3",1, "Book2",3, "Book1",2]}, "facet_ranges":{}, "facet_intervals":{}, "facet_heatmaps":}}

I've looked at the code, and it's clearly an issue there:

org.apache.solr.request.SimpleFacets#getListedTermCounts

for (String term : terms) {
    int count = searcher.numDocs(ft.getFieldQuery(null, sf, term), parsed.docs);
    res.add(term, count);
}

it's just basically iterating over terms and don't do any sorting at all.
