With VisualEditor on the page https://test2.wikipedia.org/w/index.php?title=Drong-7&oldid=161406&veaction=edit
Put the prompt just after (à tester)
delete with successives backspace (à tester) up to the prompt disappear next to website (don't touch website - official website stays not highlight)
Then Save page
Then Resume editing
Then the wizard is completely blocked (and the page)

Since somebody changed the article a very strange thing appears; When you edit the first contribution in the history with VisualEditor the article is completely blank but when you switch to wikitext the text is there : https://test2.wikipedia.org/wiki/Drong-7
I've made a new example for the first incident : https://test2.wikipedia.org/wiki/Drong-8
Aha, so, I think this is the 'deletion' equivalent of T110152: RESTBase doesn't purge renamed page -> VisualEditor unable to create moved page. Sorry for the trouble.
The latest revision of that page at https://test2.wikipedia.org/api/rest_v1/page/html/Drong-7/161414 *is* accessible and should be editable in VE, so the issue seems to be specific to that revision. https://en.wikipedia.org/wiki/Drong-7?oldid=161406 is readable however, so this must be some per-revision state in RESTBase's page_title storage blocking this.
Was this revision ever revdeleted or suppressed?
After https://github.com/wikimedia/restbase/pull/599 was deployed that shouldn't happen any more. Pages recreated before still wouldn't work properly and we can't do anything with that, but newer restored pages will work. Resolving.
