Description Ian 'Hixie' Hickson 2014-09-17 16:03:45 UTC 
I need to reverse engineer what browsers do with "shadows are only drawn if". Maybe consider "changing the processing model for shadows such that they only draw when the composition operator is source-over" (internal quotation marks elided). q.v.

...on Mac. Safari has yet another behaviour, which matches the spec. I haven't tried other platforms, but I suspect those are different too.

Either way, I'm removing the warning this bug was originally about.

Checked in as WHATWG revision r8813.
Check-in comment: Remove a note about a possible canvas change, since it hasn't happened for a few years now.
