JSDoc `@` in the code block is broken

[otomad]

Type: Bug

When writing CSS example code in JSDoc, the @ At-rules in CSS will break Markdown code blocks and incorrectly identify them as JSDoc tags.

Examples

If the code block is not in the @example tag

/**
 * Does system use dark theme?
 *
 * ```css
 * @media (prefers-color-scheme: dark) {
 *     color: white;
 * }
 * ```
 */
function isDarkTheme() { /* */ }

Preview:

As you can see, VSCode unexpectly added italic * * around the @media with a line break, but still in the code block.

If the code block is in the @example tag

/**
 * Does system use dark theme?
 *
 * @example
 * ```css
 * @media (prefers-color-scheme: dark) {
 *     color: white;
 * }
 * ```
 */
function isDarkTheme() { /* */ }

Preview:

As you can see, it will incorrectly identify @media CSS at-rule as JSDoc tag, and break the code block. Even displaying a pair of three grave accents (backticks) in the source code.

@ at-rules is not at the beginning of the line

/**
 * Does system use dark theme?
 *
 * @example
 * ```css
 * other @media (prefers-color-scheme: dark) {
 *     color: white;
 * }
 * ```
 */
function isDarkTheme() { /* */ }

Preview:

Even if it's not at the beginning of the line, it still won't display correctly.
