This local copy differs from the bundled PDF.js build at one call site: CanvasGraphics.executeOperatorList passes its current operator list as a second argument to operationsFilter. The PDF to Word renderer uses that list to omit drawn text from the graphics backdrop, including when rendering and getOperatorList have different intents. The JavaScript worker and supporting assets are the same PDF.js 5.6.205 distribution served from /privacy-cleaner/vendor/.
