The maintenance script to convert talk pages to Flow takes the content of the page above the first section and adds it to the Flow board header. When we ran this on officewiki (the WMF internal wiki),
- [[User:Tomasz Finc|Tomasz Finc]] became [/wiki/User:Tomasz_Finc Tomasz Finc]
- Also, the template invocation {{Template:Wikitext_talk_page_converted_to_Flow}} was turned into garbled HTML`<div class="dablink">Previous discussion was archived at <nowiki>[[{{{archive}}}]]</nowiki> on 2014-12-03.</div>`
@EBernhardson thinks these result from "the round trip from php parser wikitext to Flow wikitext. If we are configured to use html storage we shouldn't fall back to the php parser when it breaks"
