The surrounding_text event was taken and thrown away. It carries the
text around the cursor with a byte offset into it, and belongs to the
activation like the content type, so it is pending until done and
starts empty at every activate. delete_surrounding_text counts bytes
where the engine counts runes, and the frontend holds the text those
runes are in, so it measures them itself.
