Spreadsheet component doesn't work at all with jQuery 3.0.0
That might take a while judging by the look of it.
@mishoo feel free to ping @gyoshev regarding JQ3 compatibility problems
The bug is in kendo.list.js:

this.options.cascadeFrom is the empty string, and we end up calling jQuery for a "#" selector. Apparently that worked in earlier versions, but not anymore. If I add these lines here:
if (selector == "#") {
selector = "#IM_PRETTY_SURE_THIS_DOESNT_EXIST";
}
the problem is fixed, but that's not a nice solution... Maybe someone more knowledgeable about the List should take a look. /cc @ggkrustev @tapopov
I will take a look, but I am sure that the fix will be something similar
I believe this is fixed in the jquery-3 branch. Maybe cherry-pick this, so the issue is fixed now, instead of waiting for the branch to be merged?
