This should work because of this test

Expected Behavior

The Map.on('load', func2) should get called after Map.setStyle()

Actual Behavior

The Map.on('load', func2) does not get called after Map.setStyle()

Workaround

re-instantiate the map with a new stlye https://jsfiddle.net/tsuzk/6o8m9nad/1/

• This occurs on v1.9.0 so it's not a new behavior in v2.

Low, since there is a proper workaround
