The existing data about a webkit-prefixed variant in Chromium-based
browsers are because it was once a no-op from its WebKit origins. This
no-op was removed (by me) back in 2013:
https://chromium.googlesource.com/chromium/src/+/fca4e7ec60a824062589c7a3dde726cb1ccef902

Adding partial_implementation entries for this isn't going to be of
practical benefit to anyone at all, so it's just dropped instead.

Links to the Gecko and WebKit bugs are also added.
