== Steps to reproduce ==

(Simple demo attached)

1. In Chrome, load editor with only a widget in it (or at least have a
widget as first thing in the editor).
2. Without selecting an insert point in the editor, try using insertHtml
or insertElement.

== Expected result ==

The HTML should be inserted before the widget.

== Actual result ==

Fails with error "Uncaught TypeError: Cannot read property 'checkReadOnly'
of undefined"

== Other details (browser, OS, CKEditor version, installed plugins) ==

Chrome 44.0.2403.125 | Windows 10/8.1 | CKE 4.5.1 | Plugins: Widget /
Enhanced Image (any plugin that uses widget will do)

#14768 was marked as duplicate.

Problem can be reproduced from CKEditor 4.3.1 in Webkit browsers (both
Safari & Chrome). In version 4.3.0 error is {{{Cannot read property
'collapsed' of undefined}}}
