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
14
### Description
I once opened this issue (https://github.com/angular/components/issues/26656) and now coming back with another real-world-issue, that can't be solved neatly.
I have a selection with a ripple effect (the boxes in the screenshot) and some, optional, sub-options:

Now every time I hit a suboption the box' ripple effect shows up. Disabling it only on inner click and re-enabling it seams like some nasty timing problem (and even looks like [ripple gets removed on mouse down etc.]).
In my opinion there **really** is a need to be able to disabler the ripple effect for some boxes inside the ripple container. There should either be a directive for disabling it or to make things easy, like I suggested in my previous post, be able to switch from `capture` to `bubbling` so it can be disabled the _vanilla Javascript way_ (`stopPropagation`).
### Reproduction
https://stackblitz.com/edit/angular-phk79p-fyt248
### Expected Behavior
Ripple should not show up on clicking some container's child elements.
### Actual Behavior
Ripple cannot be disabled for some inner clicks.
### Environment
- Angular: 18.0.1
- CDK/Material: 18.0.0
贡献指南
调研方向
使用 Angular 18.0.1 和 CDK/Material 18.0.0 重现所链接 StackBlitz 中的嵌套点击行为,然后检查 MatRipple 的事件处理。确定如何在不使用依赖时序的变通方案的情况下,让子元素抑制父元素的 ripple。当点击指定的子元素不会触发容器 ripple,而正常点击容器仍会触发时,即表示完成。
