svg use tags also have href attributes

[leroix]

It's common to use svg's in anchor tags with xlink'ing. Occassionally, a click will target the use tag, and since it has an href attribute, recur-href will stop there instead of iterating up to the anchor tag.

Shouldn't the recur-href function check whether the element is an anchor tag?

Running into this issue as well. My urls are unexpectedly being set to [object SVGAnimatedString].

@wavejumper I saw that you replied to this thread (was notified via email), but it seems to be missing. You mentioned updating the logic, but I haven't seen any updates of this nature on master.

@levitanong Yeah, sorry about that! I only understood the nature of this problem after I made my comment.

I'll merge in @leroix PR this weekend when I get the chance. Apologies for the delay

Oh okay! Awesome. Thanks guys!
