Observed on IE10 on a local Windows 7 NL. Confirmed on crossbrowsertesting.com with IE10 on Windows 8. The editor is totally broken. Steps to reproduce: 1. Go to URL Observed: I. First displayed message ("Translating:Statistics") is marked as translated. 2. Open the editor by clicking on "Translating:Statistics" Observed: II. An empty editor is displayed. Expected: III. An editor with the current translation is displayed. 3. Close the editor Observed: IV. Message is marked as unsaved. Expected: V. Unchanged translations are not marked as unsaved. 4. Force reload the page. Observed: VI. A pop-up is displayed with the message "Are you sure you want to leave this page?" Expected: VII. No pop-up, as nothing was changed, and the page reloads. 5. Click "leave this page" to reload it. 6. Force reload the page again. Observed: VIII. A pop-up is displayed with the message "Are you sure you want to leave this page?" Expected: IX. No pop-up, as nothing was changed, and the page reloads.

The first two issues should be solved by https://gerrit.wikimedia.org/r/#/c/58217/ The issue with the pop-up on closing and reloading probably has something to with the .on( 'input propertychange', function () etc. bindings on the textarea in ext.translate.editor.js. There are two of them for some reason and they are doing strange things with the mw.translate.dirty flag.
IE<9 does not support oninput. So we used propertychange, but that will get triggered not only in content change, but in some DOM changes too. That might be the cause for wrong dirty bits. IE 9+ support oninput but it is buggy- does not detect text removal etc. So we need to write a cross browser event for this. That should fix all issues(3 to 6). Working on it.
With Gerrit change #58217, expected behaviors III and V are displayed. Expected behaviors VII and IX are not observed (VI and XIII instead).
Additional information: Step 4 and 6 do display expected behavior in IE9.

Tested on IE10 and other browsers, working.
