Core scripting breaks water taxi under bridges?

When you water taxi in a float plane, even under major steel bridges in cities like NYC, you get teleported up over 50 ft to the roadway or top of the bridge. The landing gear also auto-deploys as if it's doing you a favor. You can only tell it's doing this with crashes disabled (dev mode). Otherwise, it would probably seem like you hit an invisible wall and crashed with the black screen telling you so. I was in the scenery editor and trying to fix water elevation issues at various airport with water runways like CVP2 (with the Jacques Cartier bridge).

I realized I was wasting my time because even if the water is flatter than some of the bridges in NYC and has no terrain issues below a fully-modeled POI bridge, you still get this glitch. Does anyone know if payware bridges and scenery were able to fix this prevalent issue? I guess it was an accomplishment to let you fly under most bridges, but this seems like a case of bad scripting. If you are flying with your floats barely skimming the water, you can still get teleported. I tried various other scenarios and workarounds in the scenery editor too.
