Fonts are not resolved when using base href

### Description

I'm trying to deploy an Angular application to GitHub Pages using GitHub Actions. I've set the base href correctly, but the sources aren't showing up. The routes to get the sources ignore the base href. I've also tried specifying the deploy-url, but I get the same result.

### Minimal Reproduction

1. Create a project.
2. Add a custom font that's in the public folder.


3. Build the project with a base href and deploy it.
4. Note that the font URL ignores the base href.

### Exception or Error

### Your Environment

### Anything else relevant?

首先，使用 `public` 文件夹中的自定义字体和已配置的 base href 重现 `build` 命令。跟踪 Angular CLI 构建如何生成字体 URL，然后验证构建输出会在基路径下解析该 URL，而不是在站点根目录下解析。
