### Description

Angular material form field outline gap border is bigger with 1px than mat-form-field-outline-start, mat-form-field-outline-end classes border.

3. Take hover on form field

### Actual Behavior


### Environment

- Angular: 13.2.2
- CDK/Material: 13.2.2
- Browser(s): Google Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Windows 10

在 Windows 10 上使用 Angular Material 13.2.2，以 90% 缩放比例重现 Google Chrome 中 outline 表单字段的行为，然后定位负责 outline gap 及其边框类的实现。完成标准是：在缩小的缩放比例下进行 hover 时，outline gap 与 mat-form-field-outline-start/end 边框具有相同的宽度。
