Details:

When I write a new class in a `@` folder, if I use `classdef` and overload
`size`, the results from `rows`, `columns`, `isvector`, `issquare` are wrong.
Overloading `size` in a separate file but still keep using `classdef` does not
solve the problem. If I use the older style of class definition, these
functions work properly.

As a MWE to reproduce this, I created `@foo` (not using `classdef`) and `@baz`
(using `classdef`) and attached them here. Although both have only one field,
and the same implementation of `size`, I defined arbitrary values for each of
them. These are their results:


octave:1> size(foo()), rows(foo()), columns(foo())
ans =

    5   29

ans =  5
ans =  29
octave:2> size(baz()), rows(baz()), columns(baz())
ans =

   17   32

ans =  1
ans =  1


I am running Octave 5.2.0 configured for "x86_64-w64-mingw32" on Windows 7.
