I think this and the following line should be done via Template.apply(). One of the reasons we decided to have a Template class was that DOM attrs should be touched via unified API.

That's not true. This isn't UI. This is the engine and the element here isn't a native DOM element. We've been talking about unifying the APIs, but that never happened and I guess won't happen anytime soon.

Nice catch! I didn't notice that this isn't DOM. You're right, ofc ;-)

As above – nope. This is not a native element.

if ( is ) {
editable.addClass( 'ck-editable_focused' );
} else {
editable.removeClass( 'ck-editable_focused' );
}

return editable;
