(feat) Ignore order of HTML attributes

[ngocdaothanh]

I'm using HTML snapshot, like this:

<object
      aria-hidden="true"
      type="text/html"
      tabindex="-1"
></object>

If I change the order of the attributes, like this:

<object
      type="text/html"
      aria-hidden="true"
      tabindex="-1"
></object>

Please ignore the order by default.
