KOMA-Script and quote environments in footnotes

I’m trying to properly typeset an inline citation following a quote environment embedded in a footnote in both scrlttr2 and scrartcl. This is necessary to properly accomplish certain aspects of Bluebook-style citations. The following MWE works as expected in article and memoir but is broken in scrartcl.

MWE:

documentclass{scrartcl} % or {article} or {memoir}
begin{document}
Text.footnote{This is some footnote text that leads into a quotation. As the
first line of a paragraph, it should have a different amount of indentation
compared to subsequent lines.
begin{quote}
This is a block quote, which has the same degree of indentation across all
lines. Although this environment appears to work as expected, there is clearly
some problem as the subsequent lines demonstrate.
end{quote}
The Author, emph{The Article}, 2~textsc{Some L.J.} 110, 110 (2016). This is a
citation that is part of the same paragraph. It should have the same
indentation as the other subsequent lines.  It should not behave as a new
paragraph.par
This is a new paragraph of text. It should, as such, have the same indentation
as the first line of this footnote, and each subsequent line should have normal
indentation.}
end{document}

Result in scrartcl:

Intended formatting in article and memoir, respectively:

This is also broken in scrlttr2, which is what I actually care about, but because it’s still broken (in a different way) in letter, I’m comparing these classes.
