The issue names no source file, test, or parser entry point. Start by reproducing the left-side 易搭 JavaScript parsing case for `[...new Set]`, then locate the parser path responsible for producing `[[x, y, z]]`; done means the expression is parsed according to the expected JavaScript structure and a regression test covers it.
