Pointed Dripstone has a separate triangle shape for its mining animation

Steps to Reproduce:

1. Place a Pointed Dripstone;
2. Start mining it and closely pay attention to the animation.

Observed Results:
The mining animation is displayed in a separate (invisible) triangle shape, causing the entire thing to be scaled down and be cut off in weird ways.

Expected Results:
The mining animation is only visible when intersecting a visible pixel in the texture, without any separate shape.

Screenshots/Videos attached: Yes

Notes: Other cross models like cobweb and sweet berry bushes will display the animation in a square UV, completely disregarding the texture shape.
