<use xlink:href> does not respect <base> for local references

Reported by kdub...@mozilla.com, Apr 3 2017 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0

Steps to reproduce the problem:
1. Load the attachment

What is the expected behavior?
Per spec the disc should not be visible.
https://www.w3.org/TR/SVG2/linking.html#processingURL-absolute 

What went wrong?
The disc is visible in Chrome and Safari.

Did this work before? No 

Does this work in other browsers? No
 In Safari like in Chrome, we can see the pink disc.
In Firefox, we can't see the disc. 

Chrome version: 57.0.2987.98  Channel: stable
OS Version: OS X 10.12
Flash Version: 

So basically,

the baseURI for the use element is set with the value in the <base> element but is not used for deferencing the xlink:href.

<use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#logo" x="0" y="0"></use>

A parallel issue on the Firefox project

Basically it creates Web Compatibility issues.

Status: WontFix (was: Unconfirmed)
This was changed via  issue 470608  after we had attempted to implement the Gecko behavior in  issue 449027  and got push-back (possibly because this "broken" behavior had existed in WebKit for quite a while.)

Thanks a lot. This is a useful answer.
