No right padding on the last element in a row

[KarmaLaBelle]

I've added 10px padding to my grid, and this works fine without the polyfill in Edge. However, once the polyfill is enabled, I lose padding on the right side. The padding is also missing in the other major browsers.

Is this polyfill still in active development? As all new browsers now support the grid spec, its more relevant than ever to have a polyfill as new sites could be developed with the grid in mind. Thanks :)

I am not actively developing the polyfill. As I have proven before, I am more than glad to provide help to people who want to dig in the code and fix issues or implement features, but given I don't need the polyfill myself and do not get any return from it, I decided not to contribute to the project directly anymore, except obvious fixes.

This project was for me a way to prove by example the css polyfilling framework on top of which this project is built, but I am currently working at Microsoft in the Edge team and I'm more interested in adding capabilities to the browser that would enable faster and more correct polyfill frameworks than expanding an example of the current framework.
