Hi all,
I am also facing the same issue. I am using following version of parcel & bundle analyzer.

"parcel": "^2.8.3",
"@parcel/reporter-bundle-analyzer": "^2.8.3",

I get this when I use React lazy and suspense. Can somebody else also reproduce this please ?

I think this is actually caused by whitespace, because they are indeed not mapped:

This also explains why there is much less of "unknown sources" in minified builds.

Although my build is optimized/minified, I still get a big unknown source chunk. Any clue why this is happening?
