Comment (by buffler):

 Doesn't seem like a bug but there are a couple of ways to achieve the
 styling you're looking for pamtbaau -

 You can override {{{body}}}'s height with {{{height: auto; min-height:
 100%}}} (in addition to whatever background color/image) to get what
 you're wanting with the first issue. Or, you can instead apply a
 background to {{{#wpwrap}}}, as it already has {{{height: auto; min-
 height: 100%}}}.

 In core there's no need for {{{z-index}}} on the admin menu because
 there's no background applied to either {{{body}}} or {{{#wpwrap}}}. But
 yes, you can set {{{#adminmenuback, #adminmenuwrap { z-index: 1 } }}} as
 you already have with the second issue if you want {{{body}}} or
 {{{#wpwrap}}} to look better with a background applied.

 In summary, starting {{{custom_wp_admin_css}}} with these rules should get
 you going:

 {{{
 .body {
   height: auto;
   min-height: 100%;
   background: /* whatever background styles you want here */;
 }

 #adminmenuback,
 #adminmenuwrap {
   z-index: 1;
 }
 }}}
