Hey folks, it seems as though the ternary in transformCjsImport results in code that breaks coverage reporting:

https://github.com/vitejs/vite/blob/main/packages/vite/src/node/plugins/importAnalysis.ts#L1076

The setup to repro this is somewhat convoluted, (storybook, vitest), but I'm wondering what the recommended approach for code coverage is here.
