Citation bug with print_bibliography :filter "keyword phrase" with spaces

I think I've found another bug with citations, this time about filtering on 
keywords when printing bibliographies with the CSL processor.  Either that 
or I'm wrong about how it works.

Here's a test .bib file; note the "keyword phrase" keywords.  Filtering doesn't 
work on them.

Test.bib:

   @article{article1,
     title = {Title Here},
     author = {Denton, William},
     date = {2020-01-01},
     journaltitle = {Journal Title},
     issue = {1},
     keywords = {keyword phrase}
   }

   @article{article2,
     title = {Title Here Too},
     author = {Denton, William},
     date = {2023-11-01},
     journaltitle = {Journal Title Too},
     issue = {2},
     keywords = {keyword phrase}
   }

   @book{book1,
     title = {Mastering Emacs},
     author = {Petersen, Mickey},
     date = {2022},
     keywords = {emacs}
     }


And here's an Org file.  For exporting I'm using CSL, referring to a style in my 
Zotero directory.  Any Zotero user will have this, but I don't know how to make 
it easily reproducible for others.

### --------- Org file starts

#+bibliography: Test.bib

#+cite_export: csl ~/Zotero/styles/chicago-author-date.csl

* Text

One article: [cite:@article1].  Another article: [cite:@article2].  And a real book: [cite:@book1].

* Everything

#+print_bibliography:

* Emacs

#+print_bibliography: :keyword emacs

* Keyword phrase

#+print_bibliography: :keyword "keyword phrase"

### ---------- Org file ends

When exported to LaTeX, the complete bibliography and the Emacs bibliography are 
there, but the "keyword phrase" one isn't.  The manual says, "Values including 
spaces must be surrounded with double quotes."  I did that, but based on this it 
doesn't seem to be working.

(I'm running Org from the development branch.)
