Presumably you mean "why" rather than "whether". About that, see
https://github.com/zsh-users/zsh/blob/5ede2c55f144593c16498c3131a76e188114a9c6/Etc/FAQ.yo#L2056-L2102,
the first and penultimate paragraphs.

zsh is not a bug-for-bug reimplementation of bash.
As to a workaround, you don't specify what -a should do, but perhaps this:
disown %${(k)^jobstates[(R)suspended:*]}
The references for that are spread across several parts of the manual
(zshexpn(1) for ${^foo}, zshmodules(1) for $jobstates, etc), but in a
nutshell, it disowns the jobs that are listed as "suspended" in
$jobstates.
You can even syntactic sugar that:
function disown() {
if [[ $# -eq 1 && #1 == -a ]] ; then set -- %${(k)^jobstates[(R)suspended:*]} ; fi
builtin disown "$@"
}
