All X-shaped blocks in Java Edition, their textures look will never flip horizontally no matter which direction they are viewed from.

But in Bedrock, some textures will flip horizontally then cause axisymmetric in visual:

Grass, Fern, Flowers Except Pitcher Plants), Dead Bush, Saplings, Bamboo Spling, Corals, Amethyst Buds, Amethyst Cluster, Cobweb, Weeping Vine, Twisting Vine, Hanging Roots, Warped Roots, Crimson Roots, Nether Sprouts, (Flowering) Azalea (Bottom Model), Kelp, Campfire, Soul Campfire, Sweet Berry Bushes, Mangrove Propagule.

I noticed develpers have solved this problem in some new X-shaped blocks like Pitcher Plants, Pointed Dripstone, Cave Vines, so the blocks using outdated blockshapes and render methods, they should be updated because axisymmetric is ugly if watch the model carefully.
