Yes, the problem is present for 2.0-alpha-2015-04-13. But it looks trickier than I thought. The steps for reproducing the bug are applied only to couple of first edits
- Edit a page - Save it
- The saved page displays the previous, unedited version of a page.
- Perform a search for the same page - the page is displayed with not updated content.
- Load the page from History - the page is not updated either.
The same scenario when updates are done on desktop wiki.
Some sort of delayed page caching?
The issue does not happen in 2.0-r-2015-03-23.
