Research direction
Start by running the esprima.parse reproduction and read the linked TC39 specification and ESTree export-all declaration reference. Add parsing support for the shown ES2020 export form so it produces a syntax tree matching the referenced ESTree shape, then verify the reproduction no longer reports an unexpected token.
