关于使用 compiler-sfc 编译 script setup ts 文件的问题

[code-farmer-i]

Version

3.2.6

Reproduction link

https://gitee.com/ckang1229/vue-next-script-setup-issuse

Steps to reproduce

yarn
node build.js

What is expected?

props的type属性是可选的，导致生成dts文件时报错

What is actually happening?

将withDefaults.vue编译成withDefaults.ts后，props的type属性的类型应该不是可选的

Could you describe the error in more detail?

[code-farmer-i]

Use withDefaults to define attributes in script setup, and the type inference is incorrect after compile-sfc is compiled into ts file.

in sfc file

in ts file

I think it should not contain optional flags
