描述

### Description

Rendering MatChips within a MatChipGrid using NgTemplateOutlet breaks the floating label.

### Reproduction

StackBlitz link:
https://stackblitz.com/edit/itsykq?file=src%2Fexample%2Fchips-form-control-example.ts

### Expected Behavior

I expected the rendered chip template to work as normal chip.

### Actual Behavior

What happens is that when we click away from the input field, the float label floats down, making the label obstructed by the chips added.

### Environment

- Angular: 17.1
- CDK/Material: 17.1
- Browser(s): Chrome
- Operating System: macOS

首先运行链接的 StackBlitz 复现，并检查其中描述的 MatFormField、MatChipGrid 和 NgTemplateOutlet 交互。比较在输入框外点击前后浮动标签的行为；当渲染出的 chips 表现正常，且标签保持正确浮动而不被遮挡时，即表示完成。
