The "edit warning" feature of the Vector skin does not pop up a warning when the user uses the SimpleSearch box. Use case:
- Edit any article.
- Make a change in the edit box but do not save.
- (Optional) Click the "History" link: confirm that you get a proper edit warning. Cancel it.
- Remaining on the edit page, type text into the search box and press Enter.
- You leave the edit page without a warning, even though the text is modified.
You have now lost your unsaved work.
