Ember验收测试单独运行正常，批量运行除首个外全部失败

我有5个验收测试，单独运行时全部通过，但批量运行时，只有第一个测试能正常执行，其余测试均无法渲染应用，导致全部失败。

已做排查：

• 检查过未完成的等待器及应用状态稳定性，未发现异常
• 已在代码异步操作部分添加waitFor声明，确保所有操作完成
• 所有请求均通过MSW模拟，且每个测试都会启动mock service worker

相关依赖版本：

"@ember/test-helpers": "^2.8.1", "qunit": "^2.17.2", "qunit-dom": "^1.6.0", "ember-qunit": "^5.1.5", "ember-source": "~3.28.8", "ember-cli": "~3.28.5"

以下是包含3个测试的验收测试文件示例，批量运行时第一个测试表现正常，后续测试均因无法渲染而失败：
