What did you expect to happen?

I expect no linting error in all 3 samples above, because I have added "inheritAttrs" in all of them.

I expect this rule to work with Vue class component.

What actually happened?

In first 2 cases I get linting error: Set "inheritAttrs" to false

In case 3 error disappears.

This rule is not yet tuned to work with Vue class components.

Repository to reproduce this issue

Vue Class Component is no longer actively maintained and not recommended for Vue 3: https://class-component.vuejs.org/

This library is no longer actively maintained. It is no longer recommend to use Class-based components in Vue 3. The recommended way to use Vue 3 in large applications is Single-File Components, Composition API, and <script setup>.

So I suggest to not invest time in eslint-plugin-vue to start supporting this.
