Add a slight delay to the display of spinners
Spinners are a great affordance to indicate items that require time to load/process. However, seeing too many or flashing (show up briefly then disappear) spinners can have a negative impact on a users perception of system performance.
Add a slight delay to the display of spinners. This will eliminate flashing and ensure spinners are only shown on items as intended. We can use a CSS animation to apply this behavior to all spinners. Suggested delay of 0.5s.
