Expected Behavior

Inside a library using include_subdirs unqualified, a module X can be moved from one folder to another, with Dune re-running melc on the dependents of X so that their paths to JS imports can be updated.

Actual Behavior

Moving the module X leaves the dependents untouched, so any bundler like Webpack or Esbuild will fail because the import path to X these dependents are using still points to the old folder path.
