Reduce loading indicator delay (#3467)

The loading indicator currently waits for 0.5 seconds before displaying
to prevent a flicker if data loads relatively quickly. The current
half-second wait makes it look slow in my opinion, and I think a 0.2
second wait improves the experience while still addressing the flicker
issue.
