title: Vue, SVG element doesn't updates in Firefox
body: <p>This is the example <a href="https://codesandbox.io/s/4xwv953mv0" rel="nofollow noreferrer">https://codesandbox.io/s/4xwv953mv0</a></p>
  
  <p>There are three lines. The original one is hidden the second linked to it by id xlink:href="#line", the third links the second the same way.</p>
  
  <p>Move the slider, the lines will go up in the Chrome, and only one will go up in the Firefox.</p>
  
  <p>If it is a Firefox bug what to do? Is there a way to update SVG with Vue?</p>
