No loader/process indicator on Site (de)activation
Where? -> Site Panel, "activate"/"deavtivate" button
If a user clicks on "Activate" to activate a Site the button shows no Loader icon, even if the process takes a bit longer (e.g. ~2 seconds if the tag cache is built), .
The user assumes the activation is completed, although the activation AJAX request is not.
The button needs a Loader icon as long as the (de)activation request is still unfinished.
