Problems with "Latest Test Result" and "Aggregated Test Result" links

On the main page of a free-style project that aggregates test results from downstream projects,
the "Latest Test Result" link points to
http://jenkins/job/testJob/lastCompletedBuild/testReport/ instead of
http://jenkins/job/testJob/lastCompletedBuild/aggregatedTestReport/ .
The link should also say "Latest Aggregated Test Result".

In Chrome and IE this leads to 404s. Firefox automatically shows the parent page (that's actually why I didn't notice this bug earlier).

The underlying problem is that in main.jelly the following check is always true:

${tr.class.name != 'hudson.tasks.test.AggregatedTestResultAction}

(the class name is in fact "hudson.tasks.test.AggregatedTestResultPublisher$TestResultAction" for a free-style project with aggregated test results)
and

${it.lastCompletedBuild.aggregatedTestResultAction}

always returns null, because AggregatedTestResultAction is not assigned to the job.

I'm wondering if the AggregatedTestResultAction is obsolete (eventhough MatrixTestResult extends it)?
