Issue description

The 3D editor doesn't make it possible to move or rotate an object whose scale is (0, 0, 0) using editor gizmos.

When attempting to rotate a 3D object of scale 0, the following error is also printed every frame:

core/math/basis.cpp:64 - Condition "det == 0" is true.
The axis Vector3 must be normalized.

This message isn't printed when attempting to move the 3D object though. I also can't reproduce this on 3.5.rc 3f0201335.

Steps to reproduce

Add a 3D node of any type (I tested with MeshInstance3D here).
Set its scale to Vector3(0, 0, 0).
Try to move it using editor manipulation gizmos.
