section edit can remove all other text when browser restore editform
Open, MediumPublic

Description

I have seen that a edit of a section[1] was removing all the other text on that page except the text of the section. The user say this also and repaired that page and leave the note in edit summary, that he got a http status 503 on the first save. I asume that he than ticked back in the browser and saved again (or only hit reload?), which destroyed the whole page, because that recover of the editform missed some information.

I have seen this multiply times and all people wrotes about a error and than resubmit the form. I have no idea, which information is missing in the editform here. Maybe somebody has a idea.

Steps to reproduce:

0) English Wikipedia (not using Visual Editor)

  1. Instead of editing the whole article, click "edit" link on a section only.
  1. Crash the browser (in my case Firefox 26).
  1. Restart the browser - the edited area of an article will not apply to the selected section but instead will apply to the whole article.
  1. Saving changes will therefore result into removing all data except for the selected section, see example below.

E.g.:
https://en.wikipedia.org/w/index.php?title=Tourism_in_Tamil_Nadu&diff=594673990&oldid=593730355

db: Which browser do yo use?
Problem itself is confirmed hence changing status, but it's not clear to me whether there is anything that can be done server side or if this a browser issue.

db: Which browser do yo use?

I have only see the edits on my watchlist. I have not a problem with this myself. But for another case as from the links here (a half year or so), I read about a FireFox.

Tried to reproduce but failed:

Try to crash the browser on preview or "show changes", than the url is action=submit and can make more trouble.

The text in the section should be changed before, FireFox mostly recover this changed text than.
