'@' in @example code block tries to render a custom tag

When documenting code with an '@' symbol in the @example block, jsdoc thinks the '@' is a tag and breaks the rendering of the example code

Input code

/**
 * Creates a LESS file with variable definitions based on the style dictionary
 *
 * @example
 * ```
 * @color-background-base: #f0f0f0;
 * @color-background-alt: #eeeeee;
 * ```
 */
function foo() {

}

JSDoc configuration

No configuration, also tried with the markdown plugin enabled, same thing happens.

Expected behavior

Either provide a way to escape an '@' sign with a backslash, or have jsdoc ignore any content in triple ticks so that the '@' character does not trigger a tag.

Current behavior

jsdoc reads any '@' symbol as a tag even if it is within a code example.

Your environment

Start by reproducing the supplied JSDoc 3.5.5 example with the two LESS variables inside the @example block. Trace how JSDoc parses tags and fenced example content, then establish whether escaping @ or ignoring it inside triple backticks is the intended behavior and verify that the rendered example preserves both lines.
