Screenshot of Read mode after editing

Steps to reproduce bug:

1. Edit a page
2. Insert some text or a table
3. Click "Save page" in the toolbar
4. Click "Review your changes" in the dialog
5. Click "Return to save form"
6. Click "Resume editing" in the dialog
7. Click "Read" tab from the MediaWiki navigation


Expected:

Original page re-appears.

Actual:

* The modified state from the editor persists.
* Even the highlighting is still there (e.g. can highlight different cells in the table  we just inserted).
* The "Edit" tab in the MW nav is now broken (clicking it does nothing, no exception thrown).
