Openlayers 3 map，如何在没有焦点的情况下刷新

Question

I have two similar problems with an Openlayers 3 map. They both pertain to making the map refresh/redraw when it doesn't have focus; ie when the mouse is not over it.

1) I show an outline of a country when the mouse is over it, but it becomes transparent when the mouse moves off. However, if the country is at the edge of the map view and I move the mouse off that edge of the map, the country stays outlined, because the map never sees the mouse over another area outside the country.

2) When I click on a country, it becomes permanently highlighted (ie a layer becomes visible). I have a button off the map that when clicked resets all the layers to transparent. When I click the button, nothing happens until I move the mouse back over the map, at which point the change becomes apparent and the layers disappear.

Is there a way to force the map to update when the mouse is not over it?

I have tried several options: map.redraw() , layer.redraw() , source.refresh() , map.refresh() , layer.refresh() , source.refresh() , document.getElementById("map").focus() and anything else I can find suggested to force a map to refresh, but none of them work until the mouse is moved over the map.

My mistake, simple bug. Failed to update the style directly, assuming another routine was handling it.
