How to deal with islands?

It appears that the behaviour of RGFGRID with multiple polygons as shown in this video by Dano is not present anymore in its latest iteration (I'm using the 2019.1 release, 5.05.00.59437): https://www.youtube.com/watch?v=aBFH1vWCO90&t=

 I'm not sure when this disappeared but in the RGFGRID version coming with Delft3D 4.02.03 it works as in the video. In the 2019.1 version it either makes just a grid in the island polygon or covers it with a coarse grid. 

How are islands supposed to be dealt with 'nowadays'?
