Can I make build fail if hydration will complete with mismatches?

[ms264556]

I had weird bugs in the interactive part of a page (filtering content using vue-multiselect) unless it was wrapped in a <ClientOnly> - content was being duplicated instead of replaced.

It turned out to be bad html causing hydration to complete with mismatches.

Is there a (hopefully easy) way to have docs:build fail if the deployed app would need to do hydration fixups?
Ideally docs:dev would fail too, or at least spit out some warnings, but I'll take what I can get.

It looks like this might be solved now:

• Simple example of hydration error (with repo) #4189

No, I'm not complaining about bugs in VitePress or Vue.

I want VitePress to report errors in the crappy html I've embedded within markdown pages at build time, rather than quietly repairing them at runtime.
