I have the following simple JUnit test:

  @RepeatedTest(value = 2, name = RepeatedTest.LONG_DISPLAY_NAME)
  @DisplayName("Long name")
  public void repeatLong() {
    Assertions.assertTrue(true);
  }

  @RepeatedTest(value = 2, name = RepeatedTest.SHORT_DISPLAY_NAME)
  @DisplayName("Short name")
  public void repeatShort() {
    Assertions.assertTrue(true);
  }

Here how does the Allure report for it looks like:

As you can see, name of the repeatLong test method has duplicated portion in it. I expect the name to be "Long name :: repetition 1 of 2" instead of "Long name Long name :: repetition 1 of 2".

For reference, this is how test names look in IntelliJ IDEA:

and in gradle html report:
