User Agent: Mozilla/5.0 (masking-agent; rv:17.0) Gecko/17.0 Firefox/17.0 (Nightly/Aurora)
Build ID: 20130825004001
Steps to reproduce:
I used -moz-element in the following way (test case):
<html>
<head>
<style>
#B{background-image:-moz-element(#A)}
</style>
<script>
function setBackground() {
document.getElementById("A").style.backgroundImage =
"url(data:image/gif;base64,R0lGODlhAQABAJEAAAAA" +
"/wAAAAAAAAAAACwAAAAAAQABAAAIBAABBAQAOw==)";
}
</script>
</head>
<body onload="setBackground()">
<div id="A">A</div>
<div id="B">_ ->B</div>
</body>
</html>
Actual results:
After the background of div A is modified, the background of div B fails to be updated. The update can be forced by selecting text or by events that enforce a full redraw. The update does not fail after reloading the page, probably due to caching (please consider this when trying to confirm this bug).
In other cases involving -moz-element, no means can be found to enforce redraws, hence in those cases backgrounds remain missing (details are complex and will not be discussed in this thread).
Expected results:
-moz-element is a very useful feature, but it should be perfectly reliable or it may lead to invisible background images and hidden page functionality.
Almost 4000 users of my add-ons are affected by this bug. I have post-poned the release of several new add-ons because of it.
