Bibliography elements do not respect alphabetical order

[GegznaV]

Bibliography elements in Bookdown (GitBook format) do not respect alphabetical order.

To reproduce the problem:

1. Open minimal bookdown example in RStudio.
2. Download apa.csl file and save it in project's folder.
3. In YAML header of index.Rmd, replace biblio-style: apalike with csl: "apa.csl"
4. At the end of index.Rmd, add citations in this order:

1. [@xie2015]
2. [@R-rmarkdown]
3. [@R-knitr]
4. [@R-base]
5. [@R-bookdown]

5. Build a GitBook.

The result shows, that references are in the order as they were mentioned in the text:

If I use the same sources of information in Word with Mendeley plugin for citations and the same apa.csl style, I get what I expect:

In lines 714-717 of apa.csl it is written, that the bibliography list elements should be sorted by author's name:

    <sort>
      <key macro="author" names-min="8" names-use-first="6"/>
      <key macro="issued-sort"/>
    </sort>

How could this issue be solved?

UPDATE The references in index.html are in the wrong order, but in references.html in correct one:

[yihui]

That is by design at the moment. I guess it could be changed, but I don't have time for this task, and it doesn't seem to be a high-priority issue...
