Options and tags not displaying in input and dropdown with Vue 3 migration build

[giloliveira-nmi]

Starting with v2.1.7, options and tags don't seem to display when using the Vue 3 migration build.

Steps to reproduce

1. Use Vue's migration guide to setup a migration build. In short; install "vue": "^3.1.0", "@vue/compat": "^3.1.0" and "@vue/compiler-sfc": "^3.1.0" and update vue.config.js with the following code:

   // vue.config.js
   module.exports = {
   chainWebpack: (config) => {
   config.resolve.alias.set('vue', '@vue/compat')
   
   config.module
     .rule('vue')
     .use('vue-loader')
     .tap((options) => {
       return {
         ...options,
         compilerOptions: {
           compatConfig: {
             MODE: 3
           }
         }
       }
     })
   }
   }

2. Install "vue-multiselect": "2.1.7"

Expected behaviour

Multiselect input with options and tags being displayed

Actual behaviour

Tags and options are not displaying (labels don't seem to be rendered), but aside from that it technically works.
