Highcharts 4.2.6 SVG is breaking exporting

[shirgoldbird]

Expected behaviour

When exporting a graph to PNG or JPG using our personal PHP/Batik server, the graph should export.

Actual behaviour

No errors are thrown, but a completely empty image (no data) is returned.

Live demo with steps to reproduce

Something between 4.2.5 and 4.2.6 has changed such that graphs exported from 4.2.6 now contain SVG that causes Batik to silently fail when rasterizing the SVG, likely the same issue as described here. I've attached a zip file containing the same graph, exported to SVG from both 4.2.5 and 4.2.6.

The line causing it to fail in 4.2.6 is:
<g class="highcharts-tooltip" style="cursor:default;padding:0;pointer-events:none;white-space:nowrap;" transform="translate(0,-9000000000)"

Compared to 4.2.5, which works fine:
<g class="highcharts-tooltip" style="cursor:default;padding:0;pointer-events:none;white-space:nowrap;" transform="translate(0,-9999)"

@oysteinmoseng Another case related to the tooltip hiding.

Same cause as in #5570

Any idea when 4.2.7 will be released? this export bug is pretty breaking :( .

Thank you.

We will start regression testing 4.2.7 next week, so you can expect a release in one or two weeks.

Until then, here's a drop-in fix for v4.2.6:

// Workaround for #5590
Highcharts.wrap(Highcharts.Chart.prototype, 'sanitizeSVG', function (proceed, svg) {
    return proceed.call(this, svg)
        .replace('-9000000000', '-9999');
});
