[OpenSCAD] Coordinate flips between right/left-handed

I notice that the coordinate in the preview window sometimes flips between
right-handed and left handed during rotation (by mouse). The coordinate
symbol on the left-bottom corner flips as well: 
         z                             |                              |                         
o------ y             /                            /                       
x                    z                             |                             
|                          o------ x             /                           
/                        y        
In some of my designs, the handedness is crucial. Flipping in the middle of
rotation is annoying. The data inside as well as calculation involved
remains correct (took me a while to verify that), but it just looks wrong
sometimes, and looks right sometimes.

Is it a bug or by design ? I can't see the benefit of this flipping.
