The way that the v-model syntax works has changed in Vue 3 and so our code that uses it needs to be adjusted. More details at: https://v3-migration.vuejs.org/breaking-changes/v-model.html
[Vue warn]: (deprecation COMPONENT_V_MODEL) v-model usage on component has changed in Vue 3. Component that expects to work with v-model should now use the "modelValue" prop and emit the "update:modelValue" event. You can update the usage and then opt-in to Vue 3 behavior on a per-component basis with `compatConfig: { COMPONENT_V_MODEL: false }`.
