I will try to dig into it but wanted you to be aware. If you feel there's anything I can provide to help debug this then don't hesitate to let me know.

If I understand the code in these dependencies correctly, it appears that the sourceMap has a
nullin thesourcesContentarray.According to the sourcemap spec, that's allowed:
Would it be possible for you to take a look at the generated source maps to check if there is indeed one that has a
nullinsourcesContent?If there is, I'd love to know if there's anything special about the item at the same index in the source map's
sourcesarray. That array contains the names of the sources, so I'm very curious to see which source can't be inlined.
