Cannot replicate as of 1.21.50.28. It appears the issue has been resolved.
For some reason the water as a whole in that screenshot doesn't look correct; it lacks reflections/waves and looks as it did in prior versions before the recent water updates. Note the difference in the water's appearance from my screenshot. I don't know why this would be, as you are using the same version. Do you happen to have any other texture packs applied? Just in case it makes a difference, I have also uploaded the texture pack separately from the world.
The issue hasn't been fixed - it is still present as of 1.21.30.21. The reason it appeared to work is that the dirt block ID was changed in a recent beta, which broke the code assigning a texture variation to it. I have updated the example files to instead use cobblestone as the example block.
I have confirmed that the bug still exists in 1.20.80.22.
To clarify how the provided pack works: with the "variations enabled" texture pack, if the dirt block textures appear flat without any reflections, that means it's ignoring the PBR textures which would otherwise make it appear shiny.
