[bug] WebReflection Custom Elements v1 polyfill from NPM breaks app.

[trusktr]

I'm not sure where this bug report belongs, but basically, I have only the following single line of code in my app,

import 'document-register-element'

which causes this error:

[trusktr]

Reproduction:

git clone git@github.com:trusktr/meteor --branch issue-7736 --single-branch
cd meteor
./run-dev.sh

[trusktr]

I also reported it at document-register-element: WebReflection/document-register-element#72

[WebReflection]

can anyone tell me if Meteor does some overwrite for native HTML constructors ? I don't understand what even is HTML.Raw but for sure it doesn't come from my repository.

If there is some constructor that needs to be better verified or ported to DRE overwrites please let me know and I'll fix it. I just would like to be sure that's the case.

@mitar Opened a new issue at meteor/blaze#95 because it seems the error is related to Blaze/templating which is in a separate repo (although shipped by default as part of Meteor).
