Unless I'm misunderstanding that statement, that's not what I observe 
here with zsh 5.9 from the Debian package, nor in the current git HEAD:

$ zsh --emulate sh -c 'sleep 2 && sleep 3 & echo $SECONDS'
2
$ ./Src/zsh --emulate sh -c 'sleep 2 && sleep 3 & echo $SECONDS'
2
$ zsh --version
zsh 5.9 (x86_64-debian-linux-gnu)
$ ./Src/zsh --version
zsh 5.9.0.1-dev (x86_64-pc-linux-gnu)
$ git describe
zsh-5.9-308-gd8a3bff4f
