expect.soft doesnt work with toMatchSnapshot

[tijmenvanegmond]

Describe the bug

Expect.soft doesn't seem to be respected when using toMatchSnapshot, and instead of continuing the test it terminates on failed execution.

    expect.soft({foo:"bar"}).toMatchObject({foo:"baz"})
    // execution continues
 
    expect.soft({ time: new Date() }).toMatchSnapshot()
    // execution doesn't continue here

Thank you for reporting! Your reproduction seems to be private repository(I could not access it), so I prepare the reproduction https://github.com/Shinyaigeek/vitest-repro-expect-soft instead.

In my understanding, matcher method other than snapshot testing like expect.toBe use chai.assert, so soft context which is injected via expect.soft into chai.assert is respected. However, snapshot testing matcher method does not use chai.assert and it causes this behavior.

Both of your reproductions seem incorrect. @tijmenvanegmond, I cannot access yours. @Shinyaigeek, yours doesn't have any JS files.

I managed to get expect.soft to work with the snapshot methods (except for the inline snapshot methods), so submitted a PR. Please let me know if this works for you.
