is-disabled prop does not work properly

[bmalen]

is-disabled prop still allows selection if the user clicks the associated form input label.

Steps to reproduce:

<label for="foo">Foo</label>
<ModelListSelect :is-disabled="true" id="foo" v-model="foo" :list="list" option-value="value" option-text="text"></ModelListSelect>

1. Click the label
2. Press down arrow on the keyboard to highlight the desired item
3. Press Enter
