Legacy camera years old bug - SW and SE diagonals make you walk backwards slowly

Frequency: always


The point of legacy camera is to provide normal 3rd person control one would expect from any acion combat/mmo game - with keys (and their combinations) providing movement in required directions - relatively to current camera orientation.

What works correctly: N, S, W, E, NW, NE - when using those directions, the character moves (runs) as expected.

What doesn't work correctly: SW, SE - here characters starts walking backwards at a fraction of nominal speed.

This is both incredibly frustrating and pointlessly constraining. And it makes no sense whatsoever (even more so, as W, E and S direction also make the character run as exepcted, but not SW and SE ?).
