I had a look into it.
First, please, **please!!** use plain text while providing code.
Following the link above I see *no* code at all, neither in Gilbertos initial
mail to the list.
http://lilypond.1069038.n5.nabble.com/cross-staff-chords-do-not-automatically-hide-non-default-flags-td195328.html
worked, yes, but it's tedious to search which archive displays what...
On topic:
\crossStaff reverts the style property, but not a stencil set by the user.
Those stencils, predefined in flag-styles.scm mostly don't read the
style-property at all. As opposed to the stencil defined in C++, iiuc, and the
default-flag defined in the same .scm-file
So what's the proper fix?
(1)
One could simply temporary set the stencil to #no-flag in crossStaff.
(2)
Or one could return an empty stencil for every scheme-defined stencil, if style
is 'no-flag.
That would mean to change normal-flag, mensural-flag, flat-flag,
old-straight-flag and modern-straight-flag as defined in flag-styles.scm.
The there defined default-flag looks at this condition already.
Ok, a completely independent user defined flag-stencil will likely not look at
the style-property, but we could make the procedures predefined in
flag-styles.scm respecting it. A complete new code is in the responsibility of
the programmer anyway.
So, I lean to (2), looks cleaner to me to give style 'no-flag more or less the
same weight as stencil #no-flag.
But maybe I overlook something.
Opinions?

** [issues:#4983] \crossStaff only hides default-style flags**

As reported by Gilberto Agostinho, the default behaviour of `\crossStaff` to
automatically hide flags doesn’t work for styles other than the default.
