Unfriendly behavior of the file uploader menu in the destinations

[barsv]

When I do a clean install the Imgur is selected in Destinations->Image uploader. If I navigate to
Destinations->Image uploader->File uploader I find that Dropbox is checked.
Since it is already checked I assume that there is no need to click on it to do uploads using Dropbox. But in fact I have to click on this checked Dropbox menu item. And this click removes check from Imgur, sets check on File uploader.

I think that this is a bug and the behavior should be the following:
When I do a clean install the Destinations->Image uploader->Imgur is checked, but Destinations->Image uploader->File uploader->Dropbox is not checked.
If I click on items inside Destinations->Image uploader->File uploader then the behavior must be as is, that is Destinations->Image uploader->File uploader must be checked to show me that item inside is selected.
Now if I click on items inside Destinations->Image uploader other than File uploader then all items inside File uploader must be unchecked to avoid misleading me.
If Imgur is selected and I click on Destinations->Image uploader->File uploader then some item inside must be checked automatically. If there was previous selection then it must be set. If there were no previous selections than first item in the list must be checked by default.
