When content fragmented across multiple regions has contentEditable=true, the editing cursor can get displayed in multiple regions at once when positioned near an unforced break (e.g. last or first line of fragmentainer).
In attached sample file, position cursor on the first line of text in the second region.
Cursor is displayed only on first line of second region
Cursor is displayed both on first line of second region *and* last line of first region
