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.
width += marginH;
        this.w = Math.min(
          this.maxW <= 0 ? Infinity : this.maxW,
          this.minW + 1 < width ? width : this.minW
        );
      }
      if (height && this.h === "") {
        height += marginV;
        this.h = Math.min(
          this.maxH <= 0 ? Infinity : this.maxH,
          this.minH + 1 < height ? height : this.minH
        );
      }
    }
    this[$popPara]();
    fixDimensions(this);
    setFirstUnsplittable(this);
    if (!checkDimensions(this, availableSpace)) {
      this.w = savedW;
      this.h = savedH;
      this[$popPara]();
      return HTMLResult.FAILURE;
    }
    unsetFirstUnsplittable(this);
    const style = toStyle(
      this,
      "font",
      "dimensions",
      "position",
      "rotate",
