> Please review a workaround for an accessibility issue in the JavaDoc dark theme. The color used for links in the dark theme does not have enough contrast from normal text according to WCAG 2. The workaround adds underlining to links in mixed content in the dark theme to make links easier to recognize. The change is implemented with a single nested CSS rule in the block that defines the dark theme settings.
