    const r = ref(0)

    watch(r, () => console.log('1'))
    watchEffect(() => {
      r.value
      console.log('2')
    })
    watch(r, () => console.log('3'))
    watchEffect(() => {
      r.value
      console.log('4')
    })

    r.value = 1

now the rersult is 4-3-2-1
Why not let it be 1-2-3-4?
Is there any reason?
thanks

I believe this is the problem reported in issue #7576.

I think the fix in #7748 is more accurate than the fix suggested here.
