Version

3.2.20

Reproduction link

stackblitz.com

Steps to reproduce

• Open the URL
• run vite and inspect the button
• padding windiCSS class will be px-2 py-[6px]
• Run vite build and then vite preview
• again inspect the button
• padding windiCSS class will be px-3 py-2

What is expected?

The value of prop sm on the FButton component inside Helloworld should be true in both dev and prod after build and the padding should be the same.

What is actually happening?

The value of prop sm on the FButton component inside Helloworld is true in dev and undefined prod after build so the padding is inconsistent as result

I've also found the same issues in quasar link to the issue is here https://github.com/quasarframework/quasar/issues/10943. When I rolled back to vue@2.2.19 the issue was fixed. Also while working on another project https://github.com/soulsam480/furikaeru, I found this issue this morning. on dev it works perfectly but breaks in prod after building.

Seems like duplicate of #4783, may have been solved by https://github.com/vuejs/vue-next/pull/4790
