Potential bash test -v bug with associative arrays

bash_testv_associative_arrays_with_quotes.sh

#!/usr/bin/env bash

declare -A myarray
myarray["'"]="yes"
echo ${!myarray[@]}
echo ${myarray["'"]}

[[ -v myarray["'"] ]] && echo yes || echo no  # Expected: "yes" printed. Actual: "no" printed.
# Tested on GNU bash version 4.4.20(1)-release

Looks like [[ -v myarray["\'"] ]] works even though it doesn't need escaping. The problem is when the key is obtained from a variable.
