+// This file is largely copied from `highlight/white.scss`, but modified to
+// avoid all descendant selectors (`table td`). This is because the CSS inlining
+// we use performs dramatically worse on descendant selectors than the
+// alternatives.
+// <https://gitlab.com/gitlab-org/gitlab-ee/issues/490#note_12283632>
+//
+// DO NOT ADD ANY DESCENDANT SELECTORS TO THIS FILE. Instead, use (in order of
+// preference): plain class selectors, type (element name) selectors, or
+// explicit child selectors.
