1. Projection should be hidden in the viewer. Incorrect case:

create sketch with line/arc;
create new sketch in another plane, build projection of a line from the first sketch;
create a line in the 2nd sketch, Apply
edit 2nd sketch, create coincidence between line of projection feature and point of the sketch line
Error: crash in solver
2. Action button should not accept focus.
