Error when calling which-key-show-top-level in single column mode

[a13]

I use settings from #292

When I try to call M-x which-key-show-top-level I get an error - which-key can’t show keys: There is not enough space based on your settings and frame size.

Can you give me more information? Does it depend on the size of the frame for example?

Doesn't look like it does, I wasn't able to run it even in a fullscreen-mode
