Missing result attribute in testcase element from junitxml report in Qt6

In Qt 5.15, we get <testcase> elements with a result attribute but no time or classname, but in Qt 6.4, running the same tests, we get time and classname attributes but no result!
I think this a bug/regression in Qt6's QTestLib's report generators "xunitxml" and also "junitxml".
