NxAppWebpackPlugin doesn't bundle transitive dependencies of nonBuildableLibraries

[andycmaj]

Current Behavior

Looking at 7c13ed3#diff-4bf0a91a9f97bd852e8e0b9261af2a26bcdef16778610f8feb5f07b02a14c6e5 and associated bugs, it looks like the fix only checks direct deps of the current entrypoint project being bundled by webpack.

But what if those deps also depend on internal non-buildable libraries? I'm not seeing those transitive deps being added to the bundle.

Is this expected?

Expected Behavior

Expect all degrees of transitive dependency to be bundled into webpack output.
Only seeing the direct deps bundled, while THEIR deps remain external
