[Bug 18787] Canvas fallback is not activated on script failure

No, if that was the case it would be possible to load the initial image using
for example a src attribute that a script could change later (and if that image
fails to load the fallback would be activated).

Nothing will be drawn on the canvas element without a script which means that
the canvas element is not usable without that script (could of course be spread
over several javascript files) and because of that the fallback needs to be
activated. Why not try to avoid situations when the canvas element has no
content at all (because of errors) and there is fallback content that is
hidden?

I’ve not decided if I’ll have time to try to put together a change proposal so
no TRACKERREQUEST yet.
