Why does the custom list alternative succeed in a header but fails
in a layer? A predefined alternative works perfectly in a layer.

  \setupfootertexts
    [\setups{footlist}]

  \setupbackgrounds
    [page]
    [background=layer:chapter]

  \definelayer
    [layer:chapter]
    [state=repeat]

  \setlayer
    [layer:chapter]
    {\placelist [chapter] [alternative=f, criterium=all]}            %% works
    %% {\placelist [chapter] [alternative=highlight, criterium=all]} %% fails

  \definelistalternative
    [highlight]
    [renderingsetup=list:highlight]

  \startsetups [list:highlight]
    \currentlistentrytitle
  \stopsetups

  %% works
  \startsetups [footlist]
    \placelist [chapter] [alternative=highlight, criterium=all]
  \stopsetups

  \starttext
    \startchapter [title=Alpha] \stopchapter
    \startchapter [title=Beta]  \stopchapter
    \startchapter [title=Gamma] \stopchapter
  \stoptext
