I've got a few panels that are periodically masked with a call to setLoading(true, true) (to mask just the panel body and not the header). This leaves the collapse tool in the header visible (as well as the collapse tool within the splitter for those panels contained in a border layout). If a panel is collapsed after a call to setLoading(), the load mask sticks around in the same location, at the same size. Does anyone have a good fix for this?
