You have only posted a link and a single word of text. Please use words to describe what the problem is. Are you saying that esbuild is missing test coverage for this and you just want to add a test? Or are you saying esbuild's behavior in this edge case is incorrect?

OK, when I extends config-package/lib, there is a config-package/lib.json file and also config-package/lib/ directory, lib.json should be preferred. (That's how TypeScript works).

My PR is trying to add a failing test case.

I was going to fix it on my own machine, but I don't understand why whenever I started the test progress, I can never stop it but can restart my machine... So I can not work on a fix for it.
