@vitest/coverage-istanbul runs excluded files

[MKhasib]

Describe the bug

I am migrating from jest to vitest in a private repo where I used the following config

defineConfig({
test:{
    exclude: ['**/*.vue'],
    coverage: {
      all: false,
      provider: 'istanbul',
      exclude: [
        '**/*.vue',
      ],
      include: [
        '**/*.js'
       ]

However, coverage-istanbul instrument picks up vue files used inside the .js test files and adds it to the total coverage report
Is there a way to exclude all vue files used inside .js tests from getting into the final coverage report?

Reproduction

import any .vue file inside a test .js file

@AriPerkkio Do you have any ideas on how to fix this issue? Thanks!
Ps: I read all vitest docs, debugged inside vitest instrumenting libs but with no luck

The (partial) configuration shown in description is enough to solve this. Only **/*.js files should appear in coverage report. The exclude part is not needed, as include: ['**/*.js'] already excludes *.vue.

What's vite-plugin-istanbul doing there? It's not a package that Vitest maintains. It's likely causing this issue as it doesn't use vitest.config.ts at all.

@AriPerkkio Thanks for the quick response, I tried creating a reproducible repo but it seemed vitest included in coverage is working as expected just in the new repo. I am investigating why it doesn't on the private repo(actually it does exclude some files but not all .vue files from coverage)

I will close this issue for now, thank you soo much for the help!
