Summary
After the Test262 update in #23451, parser_test262.snap shows 63 new failing negative tests. These cases expect SyntaxError for new <ImportCall>.prop, but Oxc currently accepts them.
Examples:
new import('').prop
new import.source('<module source>').prop
new import.defer('./empty_FIXTURE.js').propTest262’s rationale is that ImportCall is a CallExpression, not a NewExpression. Property access on an ImportCall remains in the CallExpression grammar, so it cannot be used as the operand of new NewExpression.
