14437	Error in Safari: this.$.document is undefined (evaluating doc.compatMode)	Johannes Spohr		"Our ErrorReporting tool reports a lot of errors of this kind, which seem to occur only in Safari after working the editor for a while.
The problem seems to be that in the lineUtils Plugin Line 328 this.win.getViewPaneSize() is called, and in dom/window.js on line 51 doc is not defined.

Exact error message is:
TypeError: undefined is not an object (evaluating 'a.compatMode')[[BR]]
1 File ""(unknown)"" line (unknown) in getViewPaneSize[[BR]]
2 File ..ckeditor/plugins/lineutils/plugin.js line 21 col 185 in queryViewport[[BR]]

We're using 4.5.7 and it only occurs in Safari on Mac."	Bug	closed	Normal		General		invalid
