Hi,
The manual says:
POSIX_BUILTINS <K> <S>
When this option is set the command builtin can be used to exe‐
cute shell builtin commands. Parameter assignments specified
before shell functions and special builtins are kept after the
command completes unless the special builtin is prefixed with
the command builtin. Special builtins are ., :, break, con‐
tinue, declare, eval, exit, export, integer, local, readonly,
return, set, shift, source, times, trap and unset.
But looks like the parameter assignment before "command special-builtin"
is kept even though POSIX_BUILTINS has been set:
% zsh -f
localhost% setopt posixbuiltins
localhost% foo=bar command export a=b
localhost% print $foo
bar
localhost%

Indeed I can confirm, it appears this either was never working or has been
broken by some recent change.
The default zsh behavior when posixbuiltins is not set, is to not keep the
assignment; that appears to work.
