Closes N/A

What I did

The newly implemented export-order loader seems to fail randomly. The parse function of es-module-lexer has to be awaited to wait for wasm being ready.

Besides that:

  • Setting enforce: 'post' option like it is done in the Vite builder
  • Updating es-module-lexer to its latest version

FYI you can do const [, exports = []] = ... to skip the first entry, and to remove the lint error.
