Open a new file.
Create a plane.
Leave it as it is and set the Viewport DIsplay to Display as Wire.

First, looks like it dissapeared. The grid seems to have priority.

If you change the view, you can see it there.

If you try to select it, the only way is through the origin. You can't select by clicking on the edges, and not even through box select.

If u do the same to a cube, u can easily select it.

And you will notice that if the plane is no longer selected (after you select the cube) it will be nearly impossible to select the plane again, now that the origin point is hidden. Even the box select won't work on the origin.
