Describe the bug

when i created a application using georaster and QWebengineview ( Qt/C++, buildt on Qt5.10 msvc2017/Qt5.15 msvc2019 )，i encounter some annoying problems： js: Uncaught ReferenceError: parseGeoraster is not defined，but it successed to run in vscode, for example: http://127.0.0.1:3000/index.html.

main.cpp

#include <QApplication>
#include <QWebEngineView>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QWebEngineView *view = new QWebEngineView();
    view->load(QUrl("qrc:/web/index.html"));
    view->show();

    return a.exec();
}

index.html

<!DOCTYPE html>
<html>

<head>
  <script src="./georaster/georaster.browser.bundle.min.js"></script>
  <script src="./jquery/jquery-3.7.1.min.js"></script>
</head>

<body>
  <div id="container">***</div>
  <script>
    window.onload = () => {

      // success
      $.getJSON('./json/demo.json', function (data) {
        document.getElementById('container').textContent = JSON.stringify(data);
      });

      // error
      $.ajax({
        url: "./tif/area.tif",
        type: 'GET',
        xhr: function () {
          var xhr = new window.XMLHttpRequest();
          xhr.responseType = 'blob';
          return xhr;
        },
        success: function (data) {
          let reader = new FileReader()
          reader.readAsArrayBuffer(data)

          reader.onload = function () {
            let arrayBuffer = reader.result;

            parseGeoraster(arrayBuffer).then(georaster => {
              const min = georaster.mins[0];
              const max = georaster.maxs[0];
              const range = georaster.ranges[0];

              document.getElementById('container').textContent = min.toString() + " " + max.toString() + " " + range.toString();
            });
          }
        }
      });

    }
  </script>
</body>
