Short description of error

If a curve object consists of multiple independent bezier splines none of which are closed they are visible as 1-pixel curves in the UI.
If you change one of them to closed (use_cyclic_u=True) then the closed curves are not visible in the UI unless the object is selected or active.

To reproduce the bug create a curve and create two splines within the curve.
Make one spline closed and the other not closed.
Have the curve panel open with the Active Spline cyclic checkbox visible.
Make sure you are in object mode.
Unselect all.
toggle the cyclic checkbox repeatedly and watch how the unclosed elements of the curve disappear and reappear from the UI.
