使用自定义主题后，角度材质动画无法正常工作

我使用的是角钢版本7和角钢版本7在我更改为自定义主题之后似乎所有作品都接受了动画垫进度条停止了应有的运动

I'm using angular material version 7 and angular version 7 After i change to custom theme It seems like all work accept the animations The mat-progress-bar stopped move like it should

这是我的进度栏

<mat-progress-bar mode="indeterminate"></mat-progress-bar>

这是自定义主题
