Inline snapshots not being created

[pechitook]

Describe the bug

Under some specific settings unkown to me yet (dependencies, maybe?), inline snapshots do not work. To be more specific:

• They are not written when there is only one toMatchInlineSnapshot assertion
• They are written to the wrong assertion when there are more than one

This happened to my first project with vite/vitest and for a while assumed that they just weren't working but trying out a new project from scratch didn't have this issue. I believe this is somewhat of an edge case, and even though I narrowed my dependencies to the bare minimum in a StackBlitz project, I cannot seem to find the root cause.

Thanks!

Reproduction

1. Go to https://stackblitz.com/edit/vitejs-vite-vxrdhg?file=tests/unit/utils/dates.spec.js&view=editor
2. Run npm run test
3. See how the second snapshot gets created with the value of the first snapshot.

More variants:

• Remove the second test block, see how vitest says the snapshot was written but it is not

I found that the problem is with the source map for .js files:

vitest/packages/vitest/src/utils/source-map.ts

Line 15 in 3199dc7

const pos = consumer.originalPositionFor({ line, column })

This line returns invalid original position. Need investigating.

Just updated to 0.15.2 and can now use inlineSnapshots in the project. Many thanks @sheremet-va 🙇
