updateChoropleth() reset true - defaultFill momentarily goes black

[DaveSimmons1234]

Hi there,

I'm having an issue with updateChoropleth()

map.updateChoropleth(filteredData, { reset: true });

filtertedData contains fillColors - that do display when I call updateChoropleth(), however momentarily the countries that become deselected go black before reaching their defaultFill color.

Any thoughts as to why this might be the case?

Thanks, Dan
