Synchronize 2 Maps

[jcsho]

hello, I have a use-case for mapbox-gl-compare plugin and this example from code sandbox only works for version 5.2.8 of react-map-gl - any later version gives a Maximum update depth exceeded error

looking at the diff produces way too many changes and I was wondering if anyone has a simple solution to synchronize the onViewportChange between 2 instances of the map?
