Prefixed Shadow DOM (deprecated)

Enables DOM tree encapsulation. Without it, widgets may inadvertently break pages by using conflicting CSS selectors, class or id names, or JavaScript variables.

Comments

This old and prefixed implementation is being deprecated, please watch out for deprecation warnings in the devtools console. We have enabled an unprefixed modern Shadow DOM implementation in M35 (see the latest spec and polymer-dev for additional details on what changed since then) Updated IE views based on http://status.modern.ie/#/ ("Under consideration"). Latest spec: see also dev.w3.org/csswg/shadow-styling/ for the styling aspects.
