- [ ] feature request
- [ ] support request => Please do not submit support request here, see note at the top of this template.

#### What is the current behavior?
The documentation says that it is posible to personalize the **package**, **class** and **method** of Behave tests in the **Package** view.
https://allurereport.org/docs/behave/

The **class** label isn't displayed in the report.


#### If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
Execute:
```
@allure.label.package:cucumber
Feature: Calculator

@allure.label.testClass:Calculator
@allure.label.testMethod:add()
Scenario Outline: Addition
Given I have a calculator
When I add "" and ""
Then the calculator returns ""

Examples:
| x | y | sum |
| 1 | 1 | 2 |
| 2 | 1 | 3 |
| 2 | 7 | 9 |

```
Generate the rapport

Open the **Package** view

Result: The **class** Calculator is not displayed in the tree

The actual tree is:
```
- cucumber
- #3 add
- #2 add
- #1 add
```
#### What is the expected behavior?
The **class** Calculator is displayed in the tree

The expected tree is:
```
- cucumber
- Calculator
- #3 add
- #2 add
- #1 add
```

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

#### Please tell us about your environment:

- Allure version: 2.26.0
- Test framework: pytest@7.4.4
- Allure adaptor: allure-pytest@2.13.2
