1339788 - xlink:href attribute of <animate> element is not honored when linked by <use> element

Status: RESOLVED DUPLICATE of bug 738574

(Core :: SVG, defect)

Description

Attachment: animateBug.zip

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170213070939

Steps to reproduce:

When we set a <use> element to target a group of elements contained in an external File, and that one of these elements is an <animate> which TargetElement has been defined through the xlink:href attribute, then the TargetElement is not found (animate doesn't work).
When the TargetElement is set implicitly, because <animate> is a child of the target, then it works fine.

Perhaps, gecko can't animate with xlink:href attribute now.

simple test case:
https://people-mozilla.org/~myoshinaga/svg/bug1339788/testcase.html

We can animate without xlink:href attribute. (The blue box of above testcase)
If we use xlink:href attribute to animate tag, we can't animate which cloned by using use tag.( The red box of above testcase)

The specification of animate tag, it allows xlink:href attribute. [1] So we will need to allow this behavior. Other User Agents is allowed this behavior. (Chrome / Safari)
