v-link no longer recognizing $index inside v-for

[tylersnyder]

The v-link component is no longer recognizing the $index variable when nested inside of a v-for. This worked previously, confirmed in vue-router@0.7.7 and 0.7.8. As of vue-router@0.7.9 this is no longer working.

The resulting URL ends up looking like /:index rather than /0

Fiddle

<li class="step" v-for="driver in drivers" track-by="$index" v-link-active>
  <a v-link="{ name: 'editDriver', params: { index: $index }}">
    {{driver.firstName}} {{driver.lastName}}
  </a>
</li>
