Research direction

The issue names no repository file or test; begin with the linked JSFiddle and the export path for custom marker URLs. Reproduce both data:image and HTTPS marker cases repeatedly, then verify that exported charts include the marker reliably rather than only about 10% of the time.

Description

bug svg export

Unexpected behavior

When exporting a chart with a custom marker: https://jsfiddle.net/sartzberger/q4uxh98r/3/ it gets exported about 10% of the times.

The marker image is provided in proper, supported image url:

marker: {
    symbol: 'url(data:image/png;base64,iVBORw0KGgoA...
},

marker: {
    symbol: 'url(https://ssg.betterinvesting.org/public/markersales-b.png)'
}
