1.7.5
Not a bug but still...

Laser tool have different behavior if click on geom to add laser pen or on background.

Click on geom - add laser pen
Click on background - nothing

It's so because of uncertain direction (normal to edge for geom and unknown for background). I direction can be set by normal to nearest edge of screen.
