Sensei menu notices badges missing background bubble when their item is active

[donnapep]

Description

Sensei admin menu notification badges lose their background pill when their menu item is the currently-active one. The count number still renders, but with no colored bubble behind it, so it reads as a bare number floating in the menu.

This affects every Sensei badge that uses core's .awaiting-mod class, including:

• Home notices count — Sensei_Home::add_admin_menu_item()
• Grading ungraded count — Sensei_Grading::grading_admin_menu() (class-sensei-grading.php)

// Home
$notices_html = ' <span class="awaiting-mod">' . (int) $notices_count . '</span>';
// Grading
$indicator_html = ' <span class="awaiting-mod">' . esc_html( (string) $ungraded_count ) . '</span>';

Root cause

The badge uses WordPress core's .awaiting-mod class. On the current top-level/first menu item, core's admin color scheme (colors.css) overrides the bubble background to match the active menu color instead of the accent blue:

#adminmenu li.current a .awaiting-mod { color: #fff; background-color: rgb(12,12,12); }

The result is a white number on the near-black active-menu background — no visible pill. Non-current items (e.g. core "Plugins") keep the standard blue bubble.

Steps to reproduce

1. Have a Sensei badge count > 0 — e.g. a Home notice, or ungraded submissions for the Grading badge.
2. Navigate to that Sensei menu item (Home or Grading) so it becomes the active menu item.
3. Observe the badge: the count shows but the blue background bubble is missing. It can also appear/disappear inconsistently when hovering the menu.

Current behavior

Badge renders as a bare number with no background pill when its Sensei menu item is active.
