Can deepmerge-ts merge circular object?

[fatihaziz]

Suggestion

adding a test like this

test(`can merge circular object`, t => {
  const x = {
    a: { b: { c: `value1`, e: `im x`} },
  } as any
  x.a.b.a = x.a 
  x.a.b.b = x.a 

  const y = {
    a: { b: { c: `value2`, d: `val2` } },
    b: { b: { c: `value2`, d: `im y` } },
  } as any
  y.b.b.b = y.b 
  y.b.b.c = y.b 

  const expected = {
    a: {
      b: {
        a: x.a,
        b: x.a,
        c: `value2`,
        d: `val2`,
        e: `im x`,
      },
    },
    b: {
      b: {
        b: y.b,
        c: y.b,
        d: `im y`,
      },
    },
  }

  const merged = deepmerge(x, y)

  t.deepEqual(merged, expected)
  t.true(merged.a.b.a === merged.a)
  t.true(merged.a.b.b === merged.a)
})

there is some reason I cant test it myself on my desktop.
