[Sugar-devel] Sugarizer Activity Set - GSOC 2016

[James Cameron]

Out of synchronisation is mismatch between button state and moon
image.  It happens on first click with empty cache or fresh browser
instance.  It does not happen on page refresh.

Reproducer:

1.  start Firefox and open
http://zhirzh.github.io/sugarizer-activity-moon/

2.  wait for loading to complete,

3.  click once in the Toggle Hemisphere View button,

Expected result: both the button and moon image should change state.

Observed result: only the button changes state.

4.  click again in the Toggle Hemisphere View button,

Observed result: both the button and moon image change state.
