strange issue wth getscreenCTM in firefox on Ubuntu

[Salik Rafiq]

I am having a strange issue with a JointJS app I'm trying to build for a client of mine.

Its very simple at the moment all there are are links of a type which I have extended.

and I am loading the links in via JSON.

When the page initially loads I get this error.

TypeError: toElem.getScreenCTM(...) is null

This is code at the error.

    /**
     * @param {SVGGElement} toElem
     * @returns {SVGMatrix}
     */
    V.prototype.getTransformToElement = function(toElem) {
        toElem = V.toNode(toElem);
        return toElem.getScreenCTM().inverse().multiply(this.node.getScreenCTM());
    };

The strange bit is if I then refresh there is no error and diagram loads.

If then hold down shift and refresh I again get the error.

Any clues. I have attached the project file which hopefully reproduces the issue for you.

: Ubuntu 14.04

  Firefox 52.0.2

  JointJS 1.1.0

Hope you can help my work is basically dead in the water at moment.

Salik.
