Kerbals can no longer jump away from ladders
KSP 1.11.0 introduced a new issue wherein holding Left Shift whilst controlling a Kerbal EVA'd on a ladder makes them slide down the ladder. This causes an issue when you try to jump backwards off a ladder by holding Left Shift and pressing Space as the sliding causes the Kerbal to not release backwards off the ladder when jumping.
This mechanic was working in 1.10.1, see video: https://www.youtube.com/watch?v=Kc1DI4m6MsU
This is the issue that was introduced in 1.11.0 and still persists in 1.11.1: https://www.youtube.com/watch?v=zaxzSVQHKIE
This action (jumping back away from a ladder) is documented here in the keybindings: https://wiki.kerbalspaceprogram.com/wiki/Key_bindings : Shift + (W/S/A/D) + Space Jump to different directions when on ladders
