Try the attached patch; does it do what you're suggesting well enough?

I meant that in some uses of tabulated-list-mode there are columns whose
default width is so narrow that, when selected for sorting, they are
immediately truncated (using the patch in my previous post), e.g. the
"Status" column in list-processes.  And the issue is exacerbated with
the current patch implementing your new suggestion: with its default
width "Status" is now truncated whether selected or not.  In such cases
it may be better to make the default width of such columns wider, which
is what my first patch did.  Then with the current patch, it will still
be truncated when the column is sufficiently narrowed with `{'.
