I observed a regression when using embedded SVG images in a report masterpage. When generating a PDF the export runs just fine, however, a PPTX export will show the text “current report item is not supported in this report format” instead of the image. This worked before and seems to have broken some weeks ago.
The bug can easily be reproduced with the default masterpage in any new KNIME report. The embedded KNIME logo comes as a SVG image and reveals the issue.
