Bug report: Unexpected collapsing delimiter in APA style

[Zeping Lee]

This test case is taken from https://apastyle.apa.org/style-grammar-guidelines/citations/basic-principles/multiple-works and the CSL style is the latest released version (2022-10-02) of apa.csl. In the output, the last delimiter should be the same as others but a semicolon is actually produced.

      + expected - actual

      -(Zhou, n.d., 2000, 2016; in press)
      +(Zhou, n.d., 2000, 2016, in press)

The full fixture is in the attached file collapse_AuthorInPress.txt because it's too long to be published here. The following

>>===== MODE =====>>

<<===== MODE =====<<

(Zhou, n.d., 2000, 2016, in press)

A possible solution is adding explicit cite-group-delimiter=", " but I'm not sure if it has side effects. @bwiernik Do you have regression tests for APA style?
