Loosen check for zero vectors in GrPathUtils::convert_noninflect_cubic_to_quads
In the repro case the conic in question has a replicated control point at the end. These points end up being slightly different by the time they get to convert_noninflect_cubic_to_quads so the initial checks for a zero vector don't fire. The following checks, in the constrainWithinTangents path, do fire however leading to a premature termination of conversion to quads.
