Documenting struct in Scribble

How do you document a field of a struct which has a #:mutable option. There is nothing about this in the documentation. I'm running racket 8.7.

Looks like this is not documented but available:

Source code:

@defstruct[region ([x real?]
                   [(callback #:mutable)
                    (or/c #f (if button?
                                 (-> any)
                                 (-> (listof (is-a?/c card<%>)) any)))]
