[exim] issue with ${reduce and ${extract

hello

This example works in exim 4.87.1:

exim -be '${reduce {b}{a aaa}{${extract{1}{ }{$value}} , $item}}'

result:
a , b

But the same example doesn't work in both exim 4.88 and exim 4.89 RC6.

result:
, b

There are no any issues with extracting fields from $item.
