This question already has an answer here:

I'm trying to patch some bidi footnote commands (\@footnotetext, \@LTRfootnotetext, and \@RTLfootnotetext) in biblatex.

The footnote patching commands in biblatex occur in an AtEndPreamble macro in biblatex.sty.

And I'm trying to use #1 as a hook in \patchcmd.

This is a combination which fails, and I'm looking for ideas as to the best way around the problem.



\@footnotetext is defined this way in bidi:

     \expandafter \zref@labelbyprops

This is in order to fix issue #412 in biblatex. See https://github.com/plk/biblatex/issues/412
