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");
    let html;
    const field = this[$getParent]()[$getParent]();
    if (this.multiLine === "") {
      this.multiLine = field instanceof Draw ? 1 : 0;
    }
    if (this.multiLine === 1) {
      html = {
        name: "textarea",
        attributes: {
          dataId: (field[$data] && field[$data][$uid]) || field[$uid],
          fieldId: field[$uid],
          class: ["xfaTextfield"],
          style,
        },
      };
    } else {
      html = {
        name: "input",
        attributes: {
          type: "text",
          dataId: (field[$data] && field[$data][$uid]) || field[$uid],
          fieldId: field[$uid],
          class: ["xfaTextfield"],
          style,
