#3929 this pr can solve this.

My understanding is that the fix was released in vite@v2.4.0-beta.1, but I'm still experiencing this problem in 2.4.0-beta.3. 🤔

I tried the above repo by 2.4.0-beta.3, it works fine, can you help provide the way to reproduce, thanks

I assumed that the example featured Tailwind's JIT mode, which is the situation where I'm experiencing this problem, but it doesn't. So never mind, the issue is probably more complex or might not be related at all, I assumed that it was because Tailwind probably adds the HTML file(s) as dependencies.

@bradlc would you try your use cases against vite@2.4.0-beta.3 and close this issue if they are covered?

Has anyone experienced full page reloads on 2.4 beta 3? Changing a class in a an SFC is triggering this. Running everything on latest/next, including Tailwind.

Edit: nevermind, I think this is related to my app as it also happens on 2.3.6. Will debug and open an issue if need be.

Going from 2.3.8 to 2.4.0-beta.3 solved this issue for me.
I'm using Tailwind 2.2 with JIT mode enabled.

I have updated the reproduction to something that still doesn't work in 2.4.0-beta.3. It looks like the issue is fixed when importing CSS from a JS file, but not when using <link rel="stylesheet">
