Short description of error
In object mode a randomly rotated object (with no transformation applied) scales in a strange way when limiting the tranformation to certain global axys, while transform orientation is set to global. Basically there's no difference in local and global tranformation while it logically should be.

Exact steps for others to reproduce the error
Just add any object, rotate it randomly in z axys and any other axys. Then try scaling it based on for example the z axys. It gets stretched in multiple directions which are not exclusively the z axys. It works perfectly in edit mode though. Maybe I'm interpreting somethin wrong.

This works as intended.
In Blender an object can only be scaled towards its axis.
Therefore if the axes are not aligned, an approximate result is obtained.
You can workaround this by making a parent with another object with axis aligned to the direction you want to scale.
