Parens incorrectly removed when cloning the result of an expression

Prettier 2.7.1

PHP Plugin 0.19.1

# Options (if any):
# our .prettierrc

    "phpVersion": "8.1",
    "printWidth": 80,
    "tabWidth": 4,
    "useTabs": false,
    "singleQuote": true,
    "trailingCommaPHP": true,
    "braceStyle": "psr-2",
    "requirePragma": false,
    "insertPragma": false
}

Input:

$questions = clone ($panel->primaryViewer()?->questions() ?? new Questions());

Output:

$questions = clone $panel->primaryViewer()?->questions() ?? new Questions();

Expected behavior:

The outermost parens are being removed by prettier, affecting behavior. Given

$questions = clone ($panel->primaryViewer()?->questions() ?? new Questions());

if $panel->primaryViewer() is null, because prettier drops the outermost parens, it ends up leaving PHP to evaluate clone null - something I'm actively guarding against with the null coalesce operator.

I expect the parens to remain in place, resulting in the ?? new Questions() to be cloned.

Empieza reproduciendo la entrada PHP indicada y comparando Prettier 2.7.1 con la salida esperada. Sigue el tratamiento que hace el formateador de los paréntesis alrededor de la clone expression; se considera terminado cuando los paréntesis exteriores se conservan, de modo que se clone la null-coalesce expression, con una prueba de regresión que cubra este caso.
