test '-v' - associative vs. normal array discrepancy - a bug ?

Good day -
Please could anyone explain why the first command below produces no output:
$ ( declare -A a=([a]=1);   if [ -v a ]; then echo yes; fi )
$ ( declare -a  a=([0]=1);  if [ -v a ]; then echo yes; fi )
yes
$
There does not appear to be any documentation about
different behaviour of -v for associative vs. normal arrays:

       -v varname
              True if the shell variable varname is set (has been
assigned a value).

Should that be ammended to :
        -v varname
              True if the shell variable varname is not an associative
array and is set
              (has been assigned a value).
or is this a bug with -v ?

I'm using bash-4.3.30(1) , but it appears also to be an issue  with
bash-4.3.11(1) .

Regards,
Jason
