13917	[IE9] tests/core/log tests are not passing on IE9 when console window is opened.	Szymon Kupś	Szymon Kupś	"Run: http://test.ckedtior.dev:1030/tests/core/log on IE9 when console window is open. Tests are not passing with `Object doesn't support this action` message. It looks like this started to happen after upgrading to new `benderjs-sinon` version. 

After short research I can say that this is connected with spying on native `console` object. "	Bug	closed	Normal	CKEditor 4.5.7	General	4.5.4	fixed	IE9
