The following code is flagged as dead (since it's *replacing* rather than updating the existing Object):
https://github.com/mozilla/pdf.js/blob/4483cba72410027acf46630ebf252ae529704476/src/core/xfa/template.js#L2336-L2339
according to the alert in https://github.com/mozilla/pdf.js/security/code-scanning/103?query=ref%3Arefs%2Fheads%2Fmaster

Looking at the surrounding code, I can see a couple of possibilities here:
 1. This is indeed just dead code, which should be removed.
 2. The code should be moved up, and placed just *above* the previous block instead.
 3. There should be other, more invasive, changes made to this code...

/cc @calixteman Which solution is correct here?
Assuming it's either option 1 or 2, I can submit a patch to fix this.
if (isLrTb && this[$extra].attempt === MAX_ATTEMPTS_FOR_LRTB_LAYOUT - 1) {

      }
      const result = this[$childrenToHTML]({
        filter,
        include: true,
      });
      if (result.success) {
        break;
      }
      if (result.isBreak()) {
        this[$popPara]();
        return result;
