Steps to reproduce:
- go to a non-existing page on testwiki
- edit in VisualEditor
- add some content and save
- open for editing again
You'll be faced with an empty edit area, the previously saved will be gone. (It's properly saved but VE does not see it.)
Neither waiting between the save and the edit nor reloading the page inbetween avoids the bug.
Seems somewhat non-deterministic - on repeated attempts to edit the page, sometimes the content does show up.
