Unable to sneak around corner ledges

The player is unable to sneak around corner ledges- see the attached video for an example. This happens even though it is possible to traverse these ledges safely by walking. It would be expected that the player can safely sneak anywhere they can safely walk (without jumping).

A fix for this issue would make it much less hazardous to cross a level corner ledge where the player is forced to sneak at the block they’re moving onto. Currently, the player can make this crossing by sneak-jumping (or walking, if they are also forced to sneak at the starting block) only if their movement when stepping off the starting block is oriented more outwards (towards the ledge) than inwards (towards the wall); thus, for a given WASD input, the range of safe facing directions is half of what it is for a corner ledge with no overhead obstructions. With the fix, players would not need to learn this surprising mechanic and could simply experiment with WASD and the mouse while holding shift until the crossing gets made.
