custom nodes within svg aren't created

[ghost]

I have an element that draws an SVG line between two HTML nodes. I'm trying to move all of these elements into a single SVG node, but the instances are never created:

Works:

<template repeat="...">
    <custom-node>
        // internal
        <svg>
            <path>

doesn't work:

<svg>
    <template repeat="...">
        <custom-node>
            // internal
             <path>

Note that in the latter case, the template repeat is applied, in that if I inspect the tree there are multiple instances of custom-node. But the Polymer controller for these elements is never instantiated.

I had some luck by wrapping the custom elements in <foreignObject>: http://jsbin.com/pigiwipa/1/edit

Anything inside of the <svg> tag is going to be in the SVG element space, and there is no SVGTemplateElement.

One workaround you can use is to put a template attribute on the svg node:

<svg template repeat="...">
  <custom-svg-node>
