As soon as the context is adopted, you get the same behavior  when you
It seems that we need to go call-by-call after all. Maybe just text APIs
should be disallowed for context-less canvas? Quickly skimming the spec, I
can't find other instances where this would be a problem.
As an aside, won't the text APIs  on Path2D have the same issue? They
are not connected to a browser context so how will they work?
