21421	Sanitize/remove admin page slug  from admin menu CSS classes	kawauso		"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."	defect (bug)	new	normal	Awaiting Review	Administration		normal
