@trusktr @Koooooo-7 May I ask what is the status of this PR? Since it resolves a major issue that blocks the usage of SSR, I really hope it could be merged soon.

[Koooooo-7]

@xiao99xiao Cause the SSR refactor has not set in place yet, it may be late to merge.

@trusktr do u think we could merge it as a patch for current SSR solution?

[trusktr]

Yeah, this is already fixed in my work. SSR is working, but not all things work yet. Namely we still need some special handling for plugins. Another issue I have is I haven't installed a VM for testing, the tests don't pass in my native OS. I will circle back again soon, i haven't forgotten!
