On-water property lines persist at water level; do not line up properly with underwater land.

Description

This is, essentially, a follow-up to https://github.com/secondlife/jira-archive-internal/issues/70948 / SL-20578

While property lines do now show on the top of the water, they persist on top of the water when water is derendered from the Advanced menu. As a result, one cannot tell where the parcel line actually is on the land itself, causing a mismatch between the floating property line and the actual property location.

It would be nice if we could see the actual location of the property, though the water, and on the actual ground if water is derendered. Alternately, rolling back the change above would be a quick method of returning at least part of this functionality, as it is vital for the Land Product Team, and Residents, to be able to accurately work with inworld land.

Reproduction steps

1. Be at a property over water.
2. Turn property lines in the viewer using World > Show > Property Lines.
   
3. Derender water from Advanced > Rendering > Water
   
4. Select ground with mouse and go into About Land
   
5. Observe the difference bwteen the floating property line and the actual property selection

Support needs to see property lines on terrain and/or water, not just water.
Suggest a debug setting or render on terrain when water rendering is disabled.
