What is the current behavior?

I executed junit test cases and got the xml output. I passed that as input to allure, noted improper test case count. When a test case is executed on different product versions, it generates testsuites, each test suite executes same test case, but on different version. allure displays them as 1, and in fact I believe the first test case was shown as retries

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

What is the expected behavior?

What is the motivation / use case for changing the behavior?

Allure version	2.2.0
