How to prevent objects from disappearing when zooming in an orthographic viewport?

My viewport is set to an orthographic wireframe top view. When I try to zoom in with the mouse wheel, at some point the objects disappear from the viewport, like if they were getting out of the ‘virtual’ camera clipping planes. Is there any way to fix this?

Surprisingly you usually need to set

#…the clipping plane of the ortho camera to a negative value…

surprising but that’s how it works.
