Bug ID: 44803
Summary: The functionality to restore the edit textarea scroll
on preview is not working
Product: MediaWiki
Version: 1.21-git
Hardware: All
OS: All
Status: NEW
Keywords: easy
Severity: trivial
Priority: Unprioritized
Component: Page editing

MediaWiki had a functionality that when you edit a page and the edit area has a
vertical scroll, when you hit preview, after the page loads again the edit area
gets scrolled to the point it was before hitting the preview button.
This is no longer working since a lot of time but I'm missing it.
In fact the code is there. See JavaScript function scrollEditBox in
resources/mediawiki.action/mediawiki.action.edit.js [1]
In fact, the edit form has a hidden input field "wpScrolltop" that is being
filled correctly when you hit submit, and the server responds back with that
field with the same value that it was submitted. Manually executing the
function restores the scroll position. So maybe the function isn't being
executed at all (maybe a JS error before it? or some other code is
changing/interfering with the scroll position of the textarea.
