Yes.  But I was wrong.

I was using `(', not `M-x dired-hide-details-mode'.
Which means I was never using it when already in
`wdired-mode'.

If I use `M-x dired-hide-details-mode' when in `wdired-mode'
I see the error you reported.

Sorry for the noise.

I was first using `(' and then turning on `wdired-mode',
not turning on `wdired-mode' and then using
`M-x dired-hide-details-mode'.

(And I was evaling `(derived-mode-p 'dired-mode)' in
`wired-mode' - which returns nil.)
