A simple call to DOMParser.parseFromString will cause an active menu to get
dismissed. This is particularly a bad bug for an application that processes XML
using XMLHTTP requests in the background because it interferes with teh UI.
Reproducible: Always
Steps to Reproduce:
1. Here's a simple page that will repro the problem:
<html>
<body onload="onLoad()">
<script>
function onLoad() {
parseXml("<foo></foo>");
setTimeout(onLoad, 1500);
}
function parseXml(xml) {
/var parser = new DOMParser();
var xmlDoc = parser.parseFromString(xml, "text/xml");
return xmlDoc;
}
</script>
</body>
</html>
2. Right click on the page.
Actual Results:
The menu will get dismissed momentarily.
Expected Results:
The parsing shouldn't interfere with the menu.
Other XML methods may do this as well (serializeToString?). I'd expect no XML
methods should affect the UI as they are completely unrelated to the UI. There
is some suspicious code in parseFromStream that messes with the event queue.
This is probably the culprit.
It not only affects the current page but any other tab or browser window. In
essence a page can create a minor DOS attack using this.

You mean the menu closes? Then this would be equivalent to bug 254894.
