Adding a link / image / macro in an empty list item in IE moves it to the beginning of the next item

Edit a page in wiki mode, set content to:

* foo
* bar

Switch to Wysiwyg, place the caret at the end of "foo", hit enter. A new list item should now be created, and the caret placed inside this item.
Try to add a link (from the link menu, following the steps and setting a label for the link), or an image or a macro, or insert a symbol.
The object will be added at the beginning of the "bar" list item.

If a space is added in the empty list item, the caret is positioned before the space (at the beginning of the list item) and the same actions are executed, everything goes fine.

The behaviour was noted on 1.8.3 and 1.8.2.
