Short description of error
When trying to snap-align a selection of polys to another object using face-snapping (with Active, Project unto self and Align rotation to target,) it only works if the edit mesh object does not have transforms (loc,rot,scl). If anything is applied in transforms, the mesh will be distorted.
Exact steps for others to reproduce the error
1- select some faces in an object with transforms (loc,rot,scl), with one active face. ( this will be the "bottom" to align against target mesh)
2- set snapping on, with face mode, Active face, project unto self and align rotation.
3- move the faces towards another objects surface
4-while placing the faces, they will be distorted.
