This might be weird but same code looks different in fiddle.sencha and jsfiddle.
I found some code on jsfiddle and wanted to add it to sencha's fiddle.
Original code is located here: http://jsfiddle.net/rixo/7GKmt/
And here is version to compare: https://fiddle.sencha.com/#fiddle/2ie
Both use same ExtJS version: 4.2.0
Is this by design or maybe a bug?
