See 2.6.2 parameter expansion:
} If a parameter expansion occurs inside double-quotes:
}
} • Pathname expansion shall not be performed on the results of the expansion.
}
} • Field splitting shall not be performed on the results of the expansion.
I'm sure there's something similar for ${a#"$b"} or case $a in ("$b")
