Assuming that this is indeed a regression, since it apparently worked before, then it’s not too difficult to imagine what could have broken this and thus also how it could be “fixed”.

However, given first of all that this code isn’t being used in the Firefox PDF Viewer and secondly that the SVG back-end is documented as being unsupported, I don’t think I can justify spending my spare-time working on this issue (since I’m not getting paid to hack on the PDF.js library).

Following up on https://github.com/mozilla/pdf.js/issues/14952#issuecomment-1152397525: If those affected by this bug are willing to compensate me for my time/knowledge, I could (pretty easily) provide a patch for this.

Please also note that since this issue was opened the SVG back-end is no longer just unmaintained/unsupported, but it’s now also been officially deprecated; see https://github.com/mozilla/pdf.js/blob/7b24931f673d68803d9dac4567ba0462ec89a835/src/display/svg.js#L468-L472

We’re pretty close to the next major PDF.js release (from 3-branch) and after that the SVG back-end will in all likelihood receive no additional work/fixes.
