PyPlot.ioff() # hide does not actually hide the command

[Datseris]

For example:

```@example plot
using DynamicalSystems
using PyPlot
PyPlot.ioff() # hide

ds = Systems.logistic()
```

does not hide the line PyPlot.ioff() # hide when it is compiled.

Notice that other hide commands work for me. For example:
savefig("logisticdiagram.png"); nothing # hide is hidden in the output

I've found something similar. Some @example blocks hide lines correctly and some don't, and I haven't found a common pattern between them yet.

Maybe fixed by #991?

Yeah, this seems likely. I'll close this. If someone still runs into this (with Documenter 0.22 or higher), we can re-open.
