Sorry for necroposting, but if it's WAI because that's how all visually transparent blocks should behave, shouldn't it also affect barrier then? Because it currently does not.

This is not a bug, animated textures need a corresponding .mcmeta file in order to be animated.
In your case, apart from glass.png, you need glass.png.mcmeta (with correct instructions inside - look for how it's done in fire_layer_0.mcmeta file, or sea_lantern.png.mcmeta, or any other animated block's case).
This issue can be closed.

Should be closed as WAI.
This is not a bug since by the game's logic you're actually one block lower - it's just a side effect of how mud, snow layers, soul sand have a different hitbox and a different collision box (which can be seen in the provided screenshots - look at Y values)
