I guess changing the fix to a suggestion that has to be manually applied makes sense here. PRs welcome for that! |

<MyButton @click="(a) => fn2(a)" />
</template>
<script setup>
function fn1(a) {}
function fn2(a, b) {}
</script> |

By default, the rule will no longer automatically fix the following two types of
