svg - How to prevent AngularJS from making lowercase HTML attributes

Question

I am trying to render some SVG with AngularJS but I can't dynamically change the viewbox of the svg element.

Angular renders a 'viewbox' attribute, but browsers expect a 'viewBox' attribute. So the result is:

<svg height="151px" width="1366px" viewBox="{{ mapViewbox }}" viewbox="-183 425 1366 151">

How can I get the result I expect:

<svg height="151px" width="1366px" viewBox="-183 425 1366 151">

Thanks.

See if this directive works:

app.directive('vbox', function() {
  return {
    link: function(scope, element, attrs) {
      attrs.$observe('vbox', function(value) {
        element.attr('viewBox', value);
      })
    }
  };
});

HTML:

<svg height="151px" width="1366px" vbox="{{ mapViewbox }}">

Plnkr. You'll need to "Inspect element" or "View source" to see the svg tag.

Update: If your app includes jQuery, see Does the attr() in jQuery force lowercase?

@Niahoo found that this worked if jQuery is included (he made an edit to this post, but for some reason, other SO moderators rejected it... I liked it though, so here it is):

 element.get(0).setAttribute("viewBox", value);
