Teleported into the sky after climbing

[Lorex]

It has happened a couple of times while climbing a hedge (once in a cemetery and now in town).
I tested it further and it looks like it can happen more likely when climbing and then releasing the forward key just at the moment you arrive at the top.

I'm not using Advanced Climbing, I've tested it with all mods disabled.

First save is before climbing the hedge, second one is after teleporting into the sky, if useful.

Yes, it's similar to this bug report: viewtopic.php?f=24&t=1863

A variant I found recently, when switching walls (say, climbing sideways around a building) and I can sometimes be sent far away laterally.
It's much harder to pull off though, I haven't found a way to reproduce it reliably.

I tried looking at the code, but it is very complex.
One interesting comment I saw is TODO: Disallow rappel when pressing back if auto climbing, I wonder if that's related to this issue...
