element.parent not a function for empty item

[asmund1]

If I have the translate keyword on an empty item (in this case a div)

    <div translate>

    </div>

I get the following error:

TypeError: element.parent is not a function

Seems like the contents() function on angular-gettext.js:221

var newContents = newWrapper.contents();

strips away the span of the element created on angular-gettext.js:219 if the span is empty (the translation is empty).

One (not very elegant) workaround is to add a space when creating the span element, which is then treated as not empty:

var newWrapper = angular.element('<span> ' + translated + '</span>');

This seems to be caused by angular/angular.js#11703
But it is still broken sometimes
