Hey and thanks for all the hard work,

Please note that this is related to this issue I've created in the dd-trace-js repository as I'm not sure who owns the responsibility for this issue: DataDog/dd-trace-js#5479

I think import-in-the-middle behaves differently from require-in-the-middle because of this line:

I think it's an optimisation to avoid sending unnecessary files to the callback but it avoids some files that should be included.

For example, when given the filename file:///<redacted>/node_modules/.pnpm/@apollo+server@4.11.3_encoding@0.1.13_graphql@16.10.0/node_modules/@apollo/server/dist/esm/ApolloServer.js

baseDir will be <redacted>/node_modules/.pnpm/@apollo+server@4.11.3_encoding@0.1.13_graphql@16.10.0/node_modules/@apollo/server

specifiers.get(filename) will be ./ApolloServer.js

So when checking !baseDir.endsWith(specifiers.get(filename)) the computation will be false as you can see ./ApolloServer.js is not present in baseDir.

If I remove the line, it works.

For the same intended behavior, require-in-the-middle will provide all the files.

Thanks in advance and have a good day.
