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.

Inizia riproducendo l'input PHP segnalato e confrontando Prettier 2.7.1 con l'output previsto. Segui la gestione da parte del formatter delle parentesi intorno alla clone expression; il lavoro è completo quando le parentesi esterne rimangono, in modo che la null-coalesce expression venga clonata, con un test di regressione che copra questo caso.
