The discussion around the attempts to resolve
https://github.com/pypa/pip/issues/2195 is probably relevant, if
you're looking for an example.

Unless I'm missing something, that's unrelated :-). The "build isolation" we're talking about here is a new feature where pip tries to use a clean python environment for the build, and that issue is about an old feature where pip tries to use a clean copy of the source directory for the build.
