Firefox 2/3 and Safari 2 clear the context's path on strokeRect/

This means that those browsers that match the current draft (eg.
Safari 3 and Opera 9.x) fail to render these websites "correctly".
How hard would it be to get those sites fixed? If there are problems
in something like PlotKit or Reflection.js, which lots of people copy
onto their own servers, then it would be a pain to break
compatibility. If it's just sites like canvaspaint.org where there is
a single copy of the code and the developer still exists and can
update it, it seems a much less significant problem to break
compatibility.
I've only seen it on major sites -- it just appears that FFX3 is
unlikely
to be updated to match the correct behaviour, which is worrying in
terms of compatibility.
Certainly I would prefer that FFX behaviour was fixed as the spec'd
behaviour is much
more technically sane.
Unfortunately it isn't really an edge case as it's a relatively
common occurance -- people expect that the rect drawing function (for
example) will clear the path, so expect clearRect
(myCanvasElement.width, myCanvasElement.height) to clear the rect and
reset the path, and other similarly exciting things :-/
Firefox also resets the path on drawImage and putImageData, unlike
Opera and Safari 3 - do people depend on that behaviour too?
That honestly never occurred to me :-O
I can't see why people would expect it to, but i wouldn't have
thought they'd think that about fill/strokeRect :-/
