 As I discovered when testing #21307, browsers won't parse a CSS class name
 with both underscores and hyphens. Instead, they handle it ''really''
 badly.

 For example: `.toplevel_page_link-manager` will affect `body` in both
 Firefox and Chrome.

 Plugin page menu items have both an ID and class generated as such, which
 seems rather redundant. I propose either dropping the redundant and only
 partly functional CSS class or standardising the menu slug to produce a
 valid class name.
