disallow confusing `v-for` and `v-if` on the same element (vue/no-confusing-v-for-v-if)

⚙️ This rule is included in "plugin:vue/recommended".
⚠️ This rule was deprecated and replaced by vue/no-use-v-if-with-v-for rule.

When they exist on the same node, v-for has a higher priority than v-if. That means the v-if will be run on each iteration of the loop separately.

https://vuejs.org/v2/guide/list.html#v-for-with-v-if

So when they exist on the same node, v-if directive should use the reference which is to the variables which are defined by the v-for directives.

📖 Rule Details

This rule reports the elements which have both v-for and v-if directives in the following cases:

The v-if directive does not use the reference which is to the variables which are defined by the v-for directives.

In that case, the v-if should be written on the wrapper element.

👎 Examples of incorrect code for this rule:

<TodoItem
  v-if="complete"
  v-for="todo in todos"
  :todo="todo"
/>

👍 Examples of correct code for this rule:
