[Bug]: Coverage report broken, methods not nested in their respective classes

[wgayk]

Version

@jest/reporters 29.7.0

Steps to reproduce

create a file listType.ts that contains:

export class FooType extends ListElementType {
  //...
  static wrapContent(content: any) {
  //...
}

export class BarType extends ListElementType {
 //...
  static wrapContent(content: any) {
 //...
}

jest.config.ts:

  collectCoverage: true,

  coverageReporters: ['text', 'text-summary', 'cobertura'],
reporters: [
      'default',
      ['jest-junit', {
         outputDirectory: 'results/test',
         outputName: 'report.xml'
      }]
   ],

Expected behavior

Jenkins plugin accepts the coverage report (as it does when we run the tests using Karma).
cobertura-coverage.xml lists said classes as classes with nested methods, so method names don't clash.

Actual behavior

org.jenkinsci.plugins.workflow.actions.ErrorAction$ErrorId: 5cdc94ce-ba8d-405d-9714-3e704ae542af
java.lang.IllegalArgumentException: There is already the same child [METHOD] wrapContent()V <0> with the name wrapContent()V in [CLASS] listType.ts <28, LINE: 3.57% (1/28)>
at PluginClassLoader for coverage//edu.hm.hafner.coverage.Node.addChild(Node.java:178)

cobertura-coverage.xml report contains:

      <class name="listType.ts" filename="src\app\listType.ts" [..snip...]>
          <methods>
[..snip...]
            <method name="FooType" hits="0" signature="()V">
              <lines>
                <line number="238" hits="0"/>
              </lines>
            </method>
            <method name="wrapContent" hits="0" signature="()V">
              <lines>
                <line number="252" hits="0"/>
              </lines>
            </method>
            <method name="getDefault" hits="0" signature="()V">
              <lines>
                <line number="262" hits="0"/>
              </lines>
            </method>
            <method name="BarType" hits="0" signature="()V">
              <lines>
                <line number="277" hits="0"/>
              </lines>
            </method>
            <method name="wrapContent" hits="0" signature="()V">
              <lines>
                <line number="288" hits="0"/>
              </lines>
            </method>

i.e.: the exported class is identified as method, the methods of this class are not nested as they should be.
