SVG plugin - unable to create element feDropShadow

Thank you for all the great work on OpenHTMLtoPDF!

I am trying to render an SVG generated by a HighCharts export server and am getting this error:

org.w3c.dom.DOMException: The current document is unable to create an element of the requested type (namespace: http://www.w3.org/2000/svg, name: feDropShadow).

Has anyone else experienced this?

I don't know enough about Batik but perhaps an upgrade to version Batik 1.17 will solve the issue?

I'm attaching the SVG file here. Any help will be greatly appreciated!
