I'm finding that attempting to toggle 'Prevent Hyphenation' in a dependent style seems inconsistent and buggy.
It's complex because of the dependency and hence triple negative situation (I think that's what I'll call it
Have you have any other reports of bugs like this?
I recall another one a while back that we discussed here, to do with colors and dependent styles, that might have been similar -- the dependent style gets overridden by the parent, even though the option of using the toggle appears to be there in the dependent style.
