Revision comparison bug (HTML passing into comparison rather than WikiText)

[levans]

I have noticed that FCKeditor seems to not work so well when reviewing versions after clicking 'undo' in the history for a page.

On the 'undo' screen MediaWiki compares 'Current revision' and 'Your Text'. 'Current revision' I assume come from the latest version of page in the database (WikiText) and 'Your Text' comes from the editor... the problem is that the content that is coming from the editor is HTML not WikiText (passing from WYSIWYG).

This makes it hard to compare and messy becuase 1 is WikiText and the other is HTML.

It is even worse when: 1) 2 users open the same page for edit at the same time 2) User 1 makes a change hits the save page button 3) User 2 makes a change and hits the save page button 4) User 2 gets a warning message saying that page has change since and give comparison... It will automatically update the editor with User 1's changes (latest version of page in database, which is WikiText). The problem is that the WikiText is put in the WYSIWYG not the 'WikiText' section.

Is there a fix for this? OR Is there any way to change the code so that the 'WikiText' is used rather than from FCKeditor WYSIWYG.

Any ideas/help appreciated!!

END NOTE: I also tested this by disabling the FCKeditor, worked fine because working with all WikiText.

Does it happen in the latest version of MW extension? I can't reproduce it on ​http://mediawiki.fckeditor.net/.
