PoP - can't get out of water in "keep5"

[inf78]

After falling down to the water cave and emerging on the other side, it seems to be impossible to get up on the ledge of the lowest pillar and 'noclip' has to be used. I played with demoness.

Tested with latest source, Linux build. GL and SW renderes, both have the same problem.

I just tried in 1.5.9 and the problem is there too. Win32 version this time, in Wine.

After torturing myself a bit with it with the latest Linux build, I was in the end able to get out of the water, but it's hit and miss.
Player has to combine DOWN+JUMP+FORWARD to be able to get up on the ledge. Problem is, that there is this underwater space under that ledge, so player gets immediatelly under that ledge when DOWN is pressed. So it has to be done from a very soft angle so that the player doesn't get under the ledge, but it still counts down to chance.

Doable, but annoying as fsck.
