Scripts show up in Explorer, but not found when using 'npm: Run Script' command

[tddschn]

I was in a single-root workspace with multiple package.jsons with different scripts defined.
Npm scripts all show up in the Explorer, but got No scripts found. when using 'npm: Run Script' command.

The output panel of npm was blank, and reloading window didn't help either.
npm.includeDirectories wasn't configured, and the package.json at the root dir doesn't have any scripts.
