Water is flowing within dirt blocks

[KPaXz]

after placing medium fertility soil in water to try and remove it, i removed some dirt and found water flowing still where the dirt was. as seen in the picture provided, you can see that water is flowing within these dirt blocks.

I found many of them waterlogged dirt blocks at high altitude only, y = 167 if that matters. The waterlogged blocks were isolated from one another though in close vicinity from each other. v1.19.7 from a world created in v1.19.0rcX.
