rune-opera has just created a new issue for
https://github.com/w3c/csswg-drafts:
== [cssom] Application of existing stylesheet when href is modified ==
Should changing the href of a fully loaded and applied stylesheet to a
slow loading url cause the current stylesheet to stop applying
immediately?
Consider the case below. Firefox drops x-green-bg.css when the href is
modified, while Chrome/Opera keeps the old style. That is, unless you
also e.g. insert a new style element into the document. Then
Chrome/Opera does the same as Firefox.
```
<!DOCTYPE html>
<link id="l" rel="stylesheet" href="x-green-bg.css">
<script>
setTimeout(() => {
l.href =
"http://localhost:8000/resources/slow-image.php?sleep=3000&name=dummy.css&mimeType=text/css&expires=no";
//var s =
document.head.appendChild(document.createElement("style"));
//s.innerHTML = "#x { color: red; }"
}, 200);
</script>
<div id="x">Green background?</div>
x-green-bg.css:
#x { background:green }
```
