Yes, it is a sub-classed text view which adds a few methods and
implements the GtkCellEditable interface.  Well, it doesn't actually
override any of the GtkCellEditable methods since that isn't necessary,
it simply tells the GType system that it can be used as a cell editable.
I wonder why vanilla GtkTextView doesn't do this.

Yep, that seems to fix the issue.  Thanks.

Maybe.  But what about cells that contain multiple lines?  If the text
view only requested enough pixels for one line, it'd still turn out to
be too small and the workaround you describe above would still be
needed.
