I agree that the above behavior is wrong.

However, I agree with Chet that the above is the correct behavior. In
this example, ${kv[@]} is outside the double quoting (because the
first double quotation is « "(" » and the second double quotation is «
")" »), and then the bare ${kv[@]} is subject to word splitting so
that "two and a half" are split into four words "two", "and", "a", and
"half". Could you describe the reason that you think this is wrong?

No, at least, the latter is correct from my perspective. And, in
my perspective, the two cases are actually completely different.
