Screenshot of bug.
Encountered in IE9 using BrowserStack "Windows 7/IE9" using latest MediaWiki and VisualEditor master via a tunnel. Could either be a browser bug we have to work around, or something on our end applicable to other browsers as well.
- Load up the "Worksheet" page.
- Trying to put the cursor in the first paragraph and add text.
It repeats the first sentence many times and causes various weird scroll/focus events to occur all over the document.
