rem unit calculation does not vary for different base font sizes #3403
Description
When Dompdf performs rem calculations the calculated value does not appear to change with the font size applied to the root (HTML) element.
For example, changing the font size for the HTML element in the following document should adjust the size of the positioned DIV, but it does not.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<style>
@page {
size: 400 400;
}
html {
font-size: 10pt;
}
#rem {
background-color: orange;
position: absolute;
inset: 10rem;
}
</style>
</head>
<body>
<div id="rem"></div>
</body>
</html>
