I have a pandoc-style Markdown text where I cite two papers by the same author in the same place:
Lorem ipsum [@Author2000;@Author2001] dolor sit amet.
This is rendered as
Lorem ipsum (Author 2001, 2000) dolor sit amet.
Why are these citations sorted this way, contradicting the sequence in my text, contradicting author-year sorting, and contradicting the sequence in which they appear in the list of references? How can I change this? Is it possible to switch off any kind of sorting and keep the order in which I specify the citations?
More information: The text is converted by pandoc with the options --filter pandoc-citeproc --csl=elsevier-harvard.csl
into latex and then processed with xelatex. The csl file can be downloaded from Zotero. Pandoc is v1.13.2, pandoc-citeproc is v0.6.
