The refresh buttons keep turning between one feed and the next (#231)

Browse Source 
A scan checks its feeds one at a time; in the gap between two the body class came off, the
icon snapped back upright and the spin restarted, many times a second with fetches ahead.
The class now comes off only after 600 ms with nothing being checked.
