"!" has a special meaning in zsh, so this behaves as expected and
documented. You need to use single quotes or drop "!" from
$histchars, if you want to disable this behavior.

See section `QUOTING` in `man zshall`, quoting from there

| Inside double quotes (""), parameter and command substitution occur,
| and `\' quotes the characters `\', ``', `"', `$', and the first
| character of $histchars (default `!').
