Sketcher: changing 'Force orthographic camera when entering edit' pref changes camera even if there is no sketch

Is there an existing issue for this?

• I have searched the existing issues

Problem description

If you change the 'Force orthographic camera when entering edit' preference the camera in the active 3D view is switched to ortho mode. It does not matter if there is a sketch or not, let alone if it is active or not. Nor does it matter if you check or uncheck this option.

Test:

1. Create a new document.
2. Switch to the Sketcher WB.
3. Change to perspective mode.
4. Change the mentioned preference.
5. Result: the active 3D view has changed to ortho mode.
