::content polyfill for VanillaJS Templates and Custom Elements

[tomalec]

It seems that

polyfill-next-selector { content: ':host #myId' }

Does not work (in IE) for VanillaJS <template>s and Custom Elements.

For <polymer-element> it works fine: http://codepen.io/robdodson/pen/FokEw/, but for some reason when I try to do the same for 🍦 it doesn't http://codepen.io/tomalec/pen/apqgr

shim-shadowdom attribute also does not help.

Is there any workaround, or am I using it wrong?
