Channel Manager breaks with anchors in SVGs

If a piece of SVG code that contains an <a> element ( test.svg) is pasted directly in ftl, say base-footer.ftl in an archetype project, the channel manager produces this JS error from app.js:

TypeError: e.slice is not a function
    at i (app-386e7157bca83b5533c5.js:5)
    at app-386e7157bca83b5533c5.js:6

The front-end's LinkProcessorService doesn't handle <a> elements well, despite this piece of code added in CHANNELMGR-287:

  run(document, internalLinkPrefixes) {
      // handle links within SVG elements
      if (url instanceof SVGAnimatedString) {
        url = url.baseVal;
      }

"instanceof " fails when it shouldn't, url.constructor.name == "SVGAnimatedString" is okay? See

Happens on 11, on 13 there was a refactor regarding external links already in CHANNELMGR-2188.
On 12, the error occurs but seems that due to other exception handling it is not shown in the JS console.
