A non-isolated knockout group starts from the backdrop under it (ISO 32000-2 §11.4.7, §11.4.8), but was drawn into a layer of its own starting transparent, so a blend mode inside it had nothing to blend with: white with /BM /Difference over magenta stayed white (#4886). Entered plainly (full opacity, no soft mask, Normal, not itself a knockout element), the group is now drawn once per blend mode its elements use. Each pass is a knockout layer composited onto the backdrop in that mode; elements of other modes clear what is under their shape instead of painting. The Normal pass finds the other modes, so a group without blend modes takes one pass as before. hayro-interpret patch 67 (Device::begin_knockout_pass / end_knockout_pass, draw_knockout_passes), hayro patch 26 (the renderer side). Test: pdfcraft-render it::knockout_backdrop, three cases failing with the fix reverted, plus an isolated-group control.
