Reproduction link

https://jsfiddle.net/0wvstw39/1/

Steps to reproduce

1. Create <input type="checkbox" :value="[1]" />
2. Bind it to an array using v-model.

What is expected?

Toggling the checkbox will add/remove the value array to the v-model array.

What is actually happening?

Toggling the checkbox adds the contents of the value array to the v-model array. Checkbox is not toggled and contents are added as many times as clicked.
