Strange bug with or without quotes

Hi,

actually I stumbled across the following bug:

Assume:
local -a pcomps=('bzip2' 'lzip')

Now try to keep matching parts:
echo "${(M)pcomps:#bzip2}" # -> ""
echo ${(M)pcomps:#bzip2}   # -> "bzip2"

For my understanding, there should be no differences between the quoted
and the unquoted version.

As I had exactly that in some checks, they was always false:
if [[ -z "${(M)pcomps:#$i}" ]]

By the way, I use zsh 5.9.

Any thoughts about that?

Regards
   Klaus
