This is also happening on mw.org. I didn't test on other production sites. It can be tested here https://www.mediawiki.org/wiki/Topic:Sp1uhl1rt1e3mpto

It seems to be related to https://gerrit.wikimedia.org/r/#/c/234667/4
We don't seem to have Flow parsoid configuration. When confirmedit is enabled, it tries to parse from html to wikitext. Since we don't have VRS config, it falls back to core parsing which doesn't support this conversion.

It's not that the config is missing. We are receiving a 500 from parsoid when converting "{{{something}}}" from html to wikitext.

It is not happening locally (mw-vagrant). With VRS, the code doesn't know if it is talking to parsoid or restbase.

This problem can be reproduce on the restbase API doc page: https://restbase-beta.wmflabs.org/en.wikipedia.beta.wmflabs.org/v1/?doc
