Inline snapshots indented at col 0 when existing inline snapshots in file

[jedrichards]

🐛 Bug Report

When a new inline snapshot is generated in a file that already contains inline snapshots, the new snapshot content is incorrectly indented far left, at column 0.

To Reproduce

The following code upon file save produces a correctly indented snapshot:

test('test', () => {
  expect(['Hello world']).toMatchInlineSnapshot()
})

Becomes -

test('test', () => {
  expect(['Hello world']).toMatchInlineSnapshot(`
    Array [
      "Hello world",
    ]
  `)
})

However, with two test blocks present, the first already containing an inline snapshot -

test('test', () => {
  expect(['Hello world']).toMatchInlineSnapshot(`
    Array [
      "Hello world",
    ]
  `)
})

test('test', () => {
  expect(['Hello world']).toMatchInlineSnapshot()
})

On save, becomes -

test('test', () => {
  expect(['Hello world']).toMatchInlineSnapshot(`
    Array [
      "Hello world",
    ]
  `)
})

test('test', () => {
  expect(['Hello world']).toMatchInlineSnapshot(`
Array [
  "Hello world",
]
`)
})

Expected behavior

In the second example above, I would expect the snapshot in the second test block to be indented the same as the first, not hard left.

I've got this as well - I'd think it's b/c of #9203, but I've attempted a revert to no effect.

I'll have a poke around to see if I can find what has caused this to regress from 24.9 - will also need to find a way to make a test; jest might already have some "run twice" tests, but not hopefully something can be hacked together.

I've bisected this, it regressed in #9278.

@G-Rath thanks for looking into it! For a test, there's no need to run twice, just have the middle example from the OP and run that

@SimenB can you assign this to me? I've got a fix incoming.
