the `coverage` in `vite.config.ts` causes unbound breakpoints when debugging internal packages

[Newbie012]

Describe the bug

When trying to debug eslint-plugin-query using breakpoints, the code breaks on the wrong breakpoints. This is probably due to the changes made moving from tsup to vite. More specifically, this line:

query/packages/eslint-plugin-query/vite.config.ts

Line 11 in ae8738a

coverage: { enabled: true, provider: 'istanbul', include: ['src/**/*'] },

When commented, the breakpoints are working as expected. I assume it happens because of how istanbul tracks the code coverage.

Your minimal, reproducible example

n/a (bug in the repo itself)

Steps to reproduce

1. clone the repo
2. pnpm i
3. set a breakpoint in one of the lines of the packages eslint-plugin-query
4. pnpm test:lib:dev
5. see that the code stopped on a different line

Expected behavior

I expected the code to stop on the breakpoints I set ahead of time regardless of the coverage settings.

How often does this bug happen?

Every time

I've seen the same lately when debugging tests. @lachlancollins can we turn coverage off in general and only turn it on when we run tests in CI ?
