描述

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

If I open a dialog in which I have a mat-tab-group component and quickly click on another tab (another mat-tab), the content of the newly opened tab is not rendered - it remains empty. It looks right in DOM.

There are several ways to quickly change a tab:
1. By touch
2. Click the mouse
3. By entering the click command in the console: document.evaluate('//html[1]/body[1]/div[1]/div[2]/div[1]/mat-dialog-container[1]/dialog-data-example-dialog[1]/div[1]/mat-tab-group[1]/mat-tab-header[1]/div[1]/div[1]/div[1]/div[2]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.click()

Fast click on tab after dialog open - bug

Slow click on tab after dialog open - correct

调研方向

从链接的 StackBlitz 复现开始,测试包含 mat-tab-group 的 mat-dialog-container,包括快速切换到另一个 mat-tab。在对话框打开期间跟踪选项卡的渲染行为;完成标准是,新选中的选项卡在触摸、鼠标和脚本点击下都能稳定显示其内容。
