npm publish triggers npm run build, but that build is not published.

[zzxoto]

I see that npm publish also does npm run build courtesy to following script in package.json file "prepublishOnly": "npm run build"

But here is the deal, if I had not explicitly npm run build before npm publish, then the build would not get published to npm.

So, either the "prepublishOnly": "npm run build" script is meaningless, or this the bug that has been overlooked.
