I just automatically installed 2.8.6-fi on top of 2.8.6 and it seems to have broken the widget menu. I can't drag and drop the widgets anymore. When I place the cursor above a widget, the pointer changes to the drag-and-drop arrows as it should, but when I try to drag, it only selects text.
I get the same behaviour in Safari and Firefox. Other sites using plain 2.8.6 work like they should.
