A few months ago I started developing for SharePoint and since the very first day I have a - very important - open question.
If you use a long running operation a loading indicator image is rendered and there is also this (epic) feature that you can disable the image if you click on it.
Does anyone has any idea why someone would add this kind of feature? You can't even bring it back if you click again.
Maybe a Microsoft employee reads this and can answer that or maybe even post the corresponding commit message ;)
Obviously this is just a question out of curiosity and not really important - but as I said it's nagging at me since the beginning... :)
