Had a report from a user of DocRaptor that the only way to set multiple backgrounds correctly when one needs to control background-position and other attributes is to set it all in a single background CSS listing. I checked out MDN here, and am using the following code as a test. So feature request is: support setting background-position separately from background.
<html>
<head>
<style>
.multi_bg_example {
height: 400px;
width: 100%;
background-image : url(https://mdn.mozillademos.org/files/11305/firefox.png),
url(https://mdn.mozillademos.org/files/11307/bubbles.png),
linear-gradient(to right, rgba(30, 75, 115, 1), rgba(255, 255, 255, 0));
background-repeat : no-repeat,
no-repeat,
no-repeat;
background-position: bottom right,
left,
right;
}
</style>
</head>
<body>
<div class="multi_bg_example"></div>
</body>
</html>
