Can't bind fabric.js canvas to global variable

[serkyen]

I just discovered this package and would like to use it with Meteor APM.

In my app, I have a fabric.js canvas.

I am having an issue where as soon as I add meteorhacks:zones package, the canvas no longer works because for some reason, this package doesn't allow binding the canvas element to a variable.

So before adding meteorhacks:zones package, this works...

var canvas = new fabric.Canvas('c');

After adding meteorhacks:zones package, I get this error...

Error: Cannot read property '_bound' of undefined TypeError: Cannot read property '_bound' of undefined at removeListener (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:524509) at klass.addOrRemove (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:533308) at klass.removeListeners (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:533324) at klass._initEventListeners (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:533291) at klass._initInteractive (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:531865) at klass.initialize (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:531590) at new klass (modules.js?hash=16b9ea92d34289051e08ade6ca413c8dd3855480:524395) at Canvas.js:79

Canvas.js:79 is this line...
var canvas = new fabric.Canvas('c');

The unusual thing is that this seems to work ok...
var canvas = new fabric.StaticCanvas('c');

Of course now the canvas is not interactive.

Any ideas why this would be happening?
