Fix T94392: 3D Cursor surface projection onto hidden geometry

Regression introduced in rB098008f42d8127d9b60717c7059d3c55a3bfada7

Previously the selected geometry was ignored along with the hidden one.

The mentioned commit caused neither the hidden nor the selected one to be ignored.

But hidden geometry needs to be ignored.
