16789	[Safari] Cannot insert widget if focused before widget on the beginning of the content	kkrzton		"== Steps to reproduce ==

1. Go to http://tests.ckeditor.dev:10462/tests/plugins/widget/manual/block.
2. Insert code snippet on the beginning of the content (classic editor).
3. Click before code snippet (so the focus goes on the beginning of the editable area and not the widget).
4. Try to insert other widget (e.g. `doublecolumn` or other code snippet).

== Expected result ==
Widget inserted.

== Actual result ==
Error is thrown `TypeError: undefined is not an object (evaluating 'b.checkReadOnly')` and no widget inserted.

== Other details (browser, OS, CKEditor version, installed plugins) ==
Safari 10, CKEditor 4.6.2 built."	Bug	confirmed	Normal		General	4.5.0
