[vishalsatam]

Name of the lexer
If there are backticks present in the code, the lexer doesn't understand when to close it and highlights all following code as if it were a string literal.

Code sample
A sample of the code that produces the bug.

const getOptionLabel = (option): string => (option.id ? `${option.name ?? USER_DEFINED} (${option.id})` : '');

/**

 *
 */
const testFunction = () => {
  // Some code
};
