In spec, longer tap filter length is not constrained when neighboring coding block uses sub-PU mode and current coding block not uses sub-PU mode.

Thanks for reporting.
One approach to fix this is to check if neighbouring block has inter_affine_flag or merge_subblock_flag equal to 1 and then apply the restriction.
I'll contact Benjamin to resolve this issue.
