Describe the bug
Ether phylium cannot be spread to create more of itself or to repair bald spots in the ground, such as the ones created by growing trees.

To Reproduce

• Place ether phylium, then place ether soil surrounding it in any arbitrary shape.
• Run /gamerule randomTickSpeed 999 to set the random tick speed to an absurdly high value. Vanilla grass spreads absurdly quickly in this environment, but ether phylium does not spread at all.
• Use bone meal on any of the ether soil blocks that are adjacent to the ether phylium, to confirm that it doesn't behave like nylium. You will not be able to even use the bone meal.

Expected behavior
Ether phylium should spread to nearby ether soil, mirroring vanilla grass block spreading behaviour.
Alternatively, you could have it require bone meal usage on adjacent ether soil blocks to spread, but, given that ether phylium seems more similar to grass to me, and that ether soil only generates in biomes with ether grass, preventing it from overgrowing adjacent, barren biomes like nylium would if it could spread, the former makes more sense to me.
