Steps to reproduce

The error occurs immediately.
P.S.: This bug can be triggered if the total number of updates to a reactive object within a v-for exceeds 100.The following code patterns will all trigger the error.

<script setup>
import { ref, onMounted } from 'vue';

const options = ref([])
onMounted(()=>{
  options.value = Array.from({ length: 34 }, () => ({}))
})
</script>
<template>
  <div v-for="(item, i) in options" :key="i">
    {{ item.a ? item.a : item.a = i }}
    {{ item.b ? item.b : item.b = i }}
    {{ item.c ? item.c : item.c = i }}
  </div>
</template>

<script setup>
import { ref, onMounted } from 'vue';

const options = ref([])
onMounted(()=>{
  options.value = Array.from({ length: 21 }, () => ({}))
})
</script>
<template>
  <div v-for="(item, i) in options" :key="i">
    {{ item.a ? item.a : item.a = i }}
    {{ item.b ? item.b : item.b = i }}
    {{ item.c ? item.c : item.c = i }}
    {{ item.d ? item.d : item.d = i }}
    {{ item.e ? item.e : item.e = i }}
  </div>
</template>

What is expected?

This issue does not occur in version 3.4.38. The goal is to prevent the error from occurring again.

What is actually happening?

It’s not confirmed, but I suspect there’s an error in the flushJobs function of runtime-core related to the calculation of count.

System Info

No response

Any additional comments?

In my local development environment, this error causes certain components that work in 3.4.38 (such as those using options in a select) to become unusable, leading to rendering issues.
