[Vue warn]: $attrs is readonly.

[jslim89]

Describe the bug

Here's my html

<vue-slider v-model="priceValues"
            :min="1" :max="10000" :interval="1"
            tooltip="always"
            :tooltip-formatter="tooltipFormatter"
            :enable-cross="false"
            class="price-range-slider mt-5"></vue-slider>

In my JS

import VueSlider from 'vue-slider-component'
import 'vue-slider-component/theme/default.css'

var app = new Vue({
    el: '#app',
    components: {
        Multiselect: window.VueMultiselect.default,
        StarRating,
        VueSlider,
    },
    data: {
        priceValues: [1, 10000],
        tooltipFormatter: v => `RM${('' + v).replace(/\B(?=(\d{3})+(?!\d))/g, ',')}`,
...

I got this 2 error

[Vue warn]: $attrs is readonly.

found in

---> <E>
       <Root>

[Vue warn]: $listeners is readonly.

       <Root>

I have no issue when use other vue component, but this component caused the warning.

Environment

• OS & Version: macOS 10.15 Catalina (19A501i)
• Vue version: v2.5.21
• Component Version: v3.0.33
