XMLHttpRequest timeout in QWebKit on Symbian too short?

According to a report on QtS60-feedback, the timeout for XMLHttpRequest may be too short in QWebKit on Symbian.
The attached examples async01.html and sync01.html cannot reproduce this, certainly because the loaded data is served very quickly. I'll ask the reporter of the issue to provide more information.
(To test, visit this page on the Anomaly test browser and open one of the two test links) Edit: Actually the test does not show the expected message box. These files need to be hosted somewhere where the mimetype of the .html files get served correctly

The question is, if the default timeout is set too short and if it can be changed programmatically.
