Describe your issue

When I use Tailwind CSS in Vite, I find that some classes don't work properly, such as w-2/10, z-4, or h-2/5. I have to restart my service before these classes take effect.

When I'm using it, I must restart the service

You can reproduce my problem through this repository. You can modify the login-content element in/ page/login/index.vue. You can try to change h-3/5 to h-3/7. You will find that it does not take effect immediately. At this time, you need to restart the service
