convert_to_screen() doesn't support network/user admin
|Reported by:||kawauso||Owned by:|
The new Network and User dashboards use the -network and -user slugs respectively in the screen ID.
When using add_contextual_help() in the context of a plugin, developers are likely to be using the string result of add_submenu_page(). This is passed to convert_to_screen() and is always treated as having no specific context, resulting in the contextual help not being displayed outside of the standard dashboard. The same is likely to apply for other uses of convert_to_screen().
