Bug 1487065 didn't use shadow DOM because the platform shadow DOM implementation wasn't mature enough.

Using shadow DOM would allow using:

  • proper slotting
  • shadow DOM stylesheet scoping

This works pretty well, however, styling still needs to be ported to shadow parts. Some tests also need to be fixed.

Thanks Tim, this is a prime candidate for SD, with all the manual "slotting" going on.
