However even if that's correct I don't understand how this test case works:
÷ 1F6D1 × 200D × 1F6D1 ÷ # ÷ [0.2] OCTAGONAL SIGN (ExtPict) × [4.0] ZERO WIDTH JOINER (ZWJ_FE) × [3.3] OCTAGONAL SIGN (ExtPict) ÷ [0.3]
Here the first two chars get rewritten with WB4 to ExtPic then if only subsequent rules are applied we end up in WB999 and a break between 200D and 1F6D1. The justification in the comment indicates to use WB3c on the ZWJ but that one should have been rewritten to ExtPict by WB4.
Best,
Daniel
