Forgot to mention that my program is LuaTeX 2.08 20210220 + ConTeXt MkIV 2021.02.23 17:47
Also I like \setupbacked for what it does (export html/xml/css), I just wasn't aware that it makes bibliography render strangely when outputting a pdf.

Dear gardeners,

I'm new to ConTeXt and would like to share a possible bug with you.

If I have the \setupbackend[export=example.xml,css=example.css] entry in my .tex file, then my bibliography renders in a strange way (text copied from pdf): 1 bfldcategoryarticle: [author: Andrej Arrow] [journal: MAPS] [keywords: context] [pages: 2-8] [title: The Font Name Mess] [volume: 40] [year: 2010]

If I remove or comment that entry out, then the bibliography renders OK (copy from pdf): 1 A. Arrow, “The Font Name Mess”, MAPS 40, 2-8, 2010.

my .tex source is:
% \setupbackend[export=example.xml,css=example.css]
\usebtxdataset[default][ref.bib]

\starttext
\cite[Arrow][Arrow]
\placelistofpublications
\stoptext

my ref.bib file:
@ARTICLE{Arrow,
  author = {Andrej Arrow},
  title = {The Font Name Mess},
  journal = {MAPS},
  year = {2010},
  volume = {40},
  pages = {2-8},
  keywords = {context},
}

Hope this helps,
best,
Andrej
