Synced up polyfills with latest angular CLI

[captaincaius]

minor changes to polyfills comments...

NOTE: I didn't do this one: angular/angular-cli@d3fa9a6#diff-7ed40e1057374060b6223a05a7046411

Is it safe for us? I didn't see any explanation/issue/etc other than the commit message, so I wanted to be conservative and ask first.

looks like the deprecated ionic keyboard is suddenly making everything red. Seems this failure is on master too. Should we backport the change in the ionic4 branch to master?

[captaincaius]

As for this branch, syncing this after merging the to-ionic4 PR into 6.x should turn this green...

For master, I submitted this PR #393 :)

Thanks, I missed this in the v6 update 😛

As of now, only the unit tests runs in JIT mode due to CLI limitations, so I would say if they removed it and if our CI running the tests is OK with that, it should be safe to include 😄

Cool beans. Good point - the comment said evergeen browsers need it, so I guess we can trust our tests to tell us :)

I see you updated this one. I'll push a different PR with it removed so we know which one we can merge :)

Oh, do you want it on master too?

[captaincaius]

yup - #394 failed, so this one wins. :)
