### Task name

PublishTestResults

### Task version

2.254.0

### Issue Description

We are using the PublishTestResults@2 task to publish results from an e2e test project that sometimes fails to run because of a package update. When this happens we do not get a result file, and would like our pipeline to fail and not just get a warning. So we activated the failTaskOnFailureToPublishResults expecting it to fail when no file is found, but it doesn't work.
Here is our config :

And here is the result :
