Steps to replicate the issue (include links if applicable):
Compare
https://en.wikivoyage.org/wiki/User_Talk%3AAsqueladd?useparsoid=0
and
https://en.wikivoyage.org/wiki/User_Talk%3AAsqueladd?useparsoid=1
What happens?:
The status line of the first post ("Latest comment: 8 years ago by Ikan Kekek in topic Thumb right") is not present on the Parsoid output
What should have happened instead?:
Parsoid should not drop content from rendering
Observation: changing the order of the Localization and ExecutePostCacheTransformHooks passes (putting "localization" after the hooks) does solve the issue. So as a "temporary fix", this might be an option.

At https://www.mediawiki.org/wiki/Topic:Y4ium5hlsqc0wm2b it was reported that replying using DiscussionTools is also broken when using Parsoid, and I think that problem has the same cause – the data about which comments exist on the page, which is stored using addJsConfigVars, gets lost. Looks the patch above fixes that as well.
