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.
const style = toStyle(this, "border", "font", "margin");
    const field = this[$getParent]()[$getParent]();
    const html = {
      name: "input",
      attributes: {
        type: "text",
        fieldId: field[$uid],
        dataId: (field[$data] && field[$data][$uid]) || field[$uid],
        class: ["xfaTextfield"],
        style,
      },
    };
    return HTMLResult.success({
      name: "label",
      attributes: {
        class: ["xfaLabel"],
      },
      children: [html],
    });
  }
}
