Language of citation keys

[pauloney]

Can anyone shed light on what is going on here?

In the first entry the citation keys are -- in the respective language of the entries:
Hoffman e Kunze (1979)
Hoffman y Kunze (1973)

In the second they use the language of the entry.
Hoffman y Kunze (1961)

In the third they use English -- which is NOT the language of the entry!
Hoffman and Kunze (1961)

I would expect that they would follow the language of the entry, but I am not sure I even understand what is happening.

I did check the portuguese.lbx file and it does contain the correct:

  and              = {{e}{e}},

With biblatex v3.20 I get

So it appears to me that each "and" uses the language of the cited entry in each case.

This is what I expected, because auto changes the language of both citations and the bibliography. That said, citations in the bibliography are always a bit tricky (see e.g. #988 and linked discussions/posts): They can mess up punctuation tracking, since the punctuation tracker is global and not local. So if anything is wrong, it could be that the answer is: Citations in the bibliography are weird.

Well, I can live with the output of 3.20. It is at least uniform on what it does. I can't upgrade at the moment, because of issue #1377, but just knowing that it will work is nice.
