Using bone meal on warped/crimson nylium can spread sprouts/roots/fungi to other grass blocks

Using bone meal on the warped/crimson nylium causes sprouts and roots of the nylium's type to grow. But if you have warped and crimson nylium next to each other and use bone meal on one of them, their sprouts can spread to each other and other grass blocks despite not growing there naturally.
