### Dynamic Height Adjustment Timer

Source: https://github.com/nickrussler/email-to-pdf-converter/blob/main/src/main/resources/header.html

This JavaScript function recursively calls itself using setTimeout to continuously post the document's maximum height to the parent window. This is crucial for iframes to correctly size themselves based on their content.

```javascript
function timer() {
  try {
    parent.postMessage(Math.max(document.body.offsetHeight, document.body.scrollHeight), '*');
  } catch (r) {
  }
  setTimeout(timer, 10);
};
timer();
```
