Research direction

Reproduce the report using the Next.js 13.5.4 setup with swc-plugin-coverage-instrument and the rendered React component described in the issue. Inspect why the export is marked covered while the component is not; done means coverage accurately reflects the component render and the existing test still reports coverage correctly.

Description

Hi, thanks for the library.

For some reason some React components that are part of the pages I'm testing don't result covered, here's an example.

CleanShot 2024-04-18 at 4  47 06@2x

The export is marked as covered but the component itself doesn't, but I am 100% sure the component is being rendered in the page. I tried to throw new Error("nyc") from it and the test failed with the expected error message.

I'm using Next.js 13.5.4 with swc-plugin-coverage-instrument.

Do you know what could be going on here?
