title: Vuejs iframe interfering with router
body: <p>I have an iframe embedded in my component. When I use</p>
  <p><code>this.$router.go(-1);</code></p>
  <p>To go back to the previous page, it makes the iframe go back to the previous page instead of the current window.</p>
  <p>It doesn't go back until it finishes going back on all the pages I visited within the iframe.</p>
  <p>How can I make vue return to the previous route/page without including the iframe's navigation?</p>
