Is it expected for after-enter to trigger when a transition wrapped in keep-alive never shows its child component?

[rzzf]

When a transition is wrapped in keep-alive, the after-enter event is triggered even though the child component has never been displayed. I’m wondering if this behavior is expected.

• 将transition包裹在kee-alive中，即使transition子组件从未显示也会触发after-enter事件是预期的吗？

Reproduction

• Click the button repeatedly, and you’ll notice that after-enter is logged in the console.
• 重复点击按钮，查看控制台可以发现输出 after-enter。
