Warning state in <b-form-input> does not change the form input

Shouldn’t the warning state modify the visual part of an input form (an orange background for instance, or something like that)?

Tested on the following code (also a CodePen) :

<div id="root">
  <b-form-input v-model="myform" :state="mystate"></b-form-input>
</div>

new Vue ({
  el: "#root",
  data: {
    myform: "",
    mystate: "warning"
  }
})

You can also do this:

<b-form-fieldset state="warning">

For release v0.18.0 (coming out very soon), we’ll have clearer documentation on this, with examples.
