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 (typeof this[$content] === "string") {
      
      
      const html = valueToHtml(this[$content]).html;
      if (this[$content].includes("\u2029")) {
        
        
        html.name = "div";
        html.children = [];
        this[$content]
          .split("\u2029")
          .map(para =>
            
            
            para.split(/[\u2028\n]/).reduce((acc, line) => {
              acc.push(
                {
                  name: "span",
                  value: line,
                },
                {
                  name: "br",
                }
              );
              return acc;
            }, [])
          )
