Steps to reproduce:
1. Open any page.
2. Click the "Article" (or whatever namespace you're in) tab, or the "Read" tab and observe that the page reloads.
3. Click "Edit".
4. Either edit and save or just cancel the edit.
5. Repeat step 2.
Expected: The page should reload (especially useful on talk pages, when you want to see whether you got an answer already).
Actual: Nothing happens.
