[WAD]1276.1 - LOS tool underwater - WAD or bug?

[laro]

Noticed a bit of weirdness in how LOS tool works underwater.

For K-128 everything works as expected, there is a ridge which blocks LOS to surface (screenshot attached).

For K-488 however when it hugs the sea floor LOS to surface seems to be limited to less than 1nm. When I decrease the depth it still looks weird (approx. 1 nm) (screen for -150 m attached). The sea floor, as much as I can inspect it is 20 m below the submarine (no ridges present nearby when i hover the cursor). Things improve when the sub goes above -100 m.

Is it WAD and due to physical factors in the model or is it a bug? Is LOS tool supposed to work underwater at all?

Still happens in 1328.8.
