[Regression] Pass type as input type for function doesn't infer the correct type

[ahnpnl]

Summary

I have this sample code

<script setup lang="ts">
interface Foo {
    callMe(option: number): void;
}

defineExpose<Foo>({
    callMe(option) {
        console.log(option)
    }
})
</script>

Starting from 0.34.3 onwards, I got the error

error TS7006: Parameter 'option' implicitly has an 'any' type.

1 <template>

This error is not correct because option here is auto inferred type as number.

The bug doesn't happen with <= 0.34.2
