Vue version

3.2.47

Link to minimal reproduction

https://stackblitz.com/edit/github-c1z4a8-we3axz?file=src/main.ts

Steps to reproduce

return { innerHTML: 'some value' } from a Vue directive via getSSRProps. innerHTML is then not propagated. (see also stackblitz example)

What is expected?

I expect innerHTML to be defined serverside so that my component is prefilled with content before rendering.

What is actually happening?

The innerHTML is not filled, which means the content stays blank (see stackblitz example)

Any additional comments?

I'm currently working rewriting some parts of our codebase from Nuxt 2 to Nuxt 3. I initially thought this was related to Nuxt but the same issue is happening in Vue 3 with SSR rendering too. I try to modify the innerHTML serverside but it seems that innerHTML is not propagated. I tried in the stackblitz example to write some content to innerHTML via getSSRProps. I'm not sure if this is a bug or intended behaviour, or perhaps there is a different way to modify innerHTML in getSSRProps?

I use webpack and have the same problem

getSSRProps does not support rendering of these properties. But I use v-html in ssr server is normal

Ah good find, seems like it's intentional indeed! I'll close this one

I think it needs to be fixed, and this only happens in optimized compilation. For client-compiled render functions it works.
