Style and View Encapsulation is best understood by seeing how each option (Emulated, Native, and None) compare to each other.
I'm wondering about this as well. I would think polyfils would make it work the same regardless of browser support? Otherwise why use Native at all?
I cannot run any beta examples - here or anywhere else - in ie to test this out. I read that you need to load the ie shim, but when I add a script tag for it ie still fails with errors in the vendor.bundle.js. Any other tips on how to get angular beta running in IE?
I ran the example in firefox. It breaks in Native mode (no console error) unless you go to about:config to enable webcomponents. It is then working the same as in chrome, though i see an inline style tag inside each todo renderer for the strikethrough style, and no shadow-root. Perhaps the developer tool simply doesn't display shadow root properly? And sorry, that still leaves the question, what is the expected behavior?
