Dead code elimination doesn't work well with nested try

Input code

let workerPool

export function compile(src, options) {
  if (process.env.CIVET_THREADS != 0) {
    const threads = Number(options.threads ?? process.env.CIVET_THREADS)
    if (!isNaN(threads) && threads > 0 && !options.sync) {
      try {
        workerPool = new WorkerPool(options.threads)
      }
      catch {
        workerPool = null
      }
    };return
  };return
}

Current output

(() => {
  // entry.js
  function compile(src, options) {
    if (0 && !isNaN(threads) && threads > 0 && !options.sync)
      try {
      } catch {
      }
  }
})();

Expected output

(() => {
})();

Additional info

Removing the try/catch block results in the expcted output.
