- Regressed in https://codereview.chromium.org/1801383002 in core/fxcodec/jbig2/JBig2_TrdProc.cpp (So not actually font related - the "text" is an image) - pdfium_test can render the PDF if I force the non-linearized rendering path.

I take back the part about the text being an image. The text looks selectable, so I'm not 100% sure and I haven't looked closer.
