Steps to reproduce:
- open article in browser window
- open same article in another browser window, edit, save changes
- edit with VE in first window
Expected result: VE show some sort of warning, and loads the newest version of the article (or maybe refuses to edit it at all).
Actual result: VE happily edits the old revision, and shows [[MediaWiki:Editingold]].
Version: unspecified
Severity: minor
