lok: sc: render expanded EditEngine when editing in-place

It's regression from:
commit 5a0839e60ac75869ad49685ca74ad6c6b49ef925
sc: lok: fix offset edit output area

When we use two views and one is editing multiline cell
after pressing F2 (in in-place mode) by adding new lines
(ctrl + enter) - we need to expand rendering area and
show additional content (which covers next cells).

This patch makes possible to render expanded are in all the
views, not only for one used for rendering.
