The page loading wheel on the top right corner remains spinning after completing an export to excel on any portlet list.
This causes confusion, the export may not have finished or looks hanging.

Steps to reproduce: 
1) Open any portlet or list view.
2) In Options, select "export to excel" (any of the 2 options) 
3) Even after the export is completed, the wheel keeps spinning.

Informational solution: refresh the page.
