#### What is the current behavior?
Each test is added 4 times in the report when using these tags :
```
allure.label.parentSuite:xxxxx
allure.label.suite:xxxxx
```

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

... allure.label.package:web_robotframework.webform_test
... allure.label.testMethod:test_fill_in_form

```

The tree of my python code source is as follows :
```
web_robotframework_playwright
|- keywords
|- webform.robot
|- tests
|- webform_page.robot
```

#### What is the expected behavior?
The test is added once
The suite view displays the metadata set in the test tags (parentSuite, suite and subsuite)

#### What is the motivation / use case for changing the behavior?
A test should by added to the report once instead of being added 4 times.

#### Please tell us about your environment:

- Allure version: 2.29.0
- Test framework: robotframework-browser@18.5.1
- Allure adaptor: allure-robotframework@2.13.5

tests/webform_page.robot と keywords/webform.robot から始め、示されている parentSuite タグと suite タグを使用して、robotframework-browser 18.5.1 と allure-robotframework 2.13.5 でレポートを再現します。レポートにテストが 1 回だけ含まれ、suite ビューに parentSuite、suite、subsuite のメタデータが表示されれば完了です。
