Unexpected result of .normalize() on already Zero vector

[eonarheim]

Steps to Reproduce

Attempt to normalize a vector of length zero

Other prior art is that Godot/Unity/Unreal all return a zero vector

• https://github.com/godotengine/godot/blob/master/core/math/vector2.cpp
• https://docs.unity3d.com/ScriptReference/Vector2.Normalize.html
• https://dev.epicgames.com/documentation/en-us/unreal-engine/BlueprintAPI/Math/Vector/Normalize?application_version=4.27

Expected Result

Return a vector copy that is also zero

Actual Result

Arbitrary direction is returned

Environment

Latest

Current Workaround

Check for zero vectors before normalizing
