Previous behavior
================
When `editable=bottom`, when we hit tab until the end of the line, the
user starts to create a new record.
But when `editable=top`, when hitting tab multiple until the end of the
line, the user starts to edit the first line that was existing before
instead of creating a new one.
New behavior
============
The behavior is consistent between both cases: the user can always
continue to edit lines one after the other.
The behavior for `editable=bottom` is not changed, but `editable=top`
continues to add lines on top one of each other.
