+/* Vendor Sales Report Menu - Hide icon/pseudo-element reliably
+   Some Magento admin menu item class names vary depending on how the
+   menu id is normalized (module and item id). Targetting the generated
+   class used by this module may not always match, which causes a
+   leftover glyph/box to appear. Use the menu link href as a reliable
+   selector and include broader admin menu selectors so the icon is
+   removed even if the class name differs. */
