Standalone component to reproduce

import React from 'react';
import { View } from 'react-native';
import {
  MapView,
  MarkerView
} from '@rnmapbox/maps';


class BugReportExample extends React.Component {
  render() {
    return (
      <MapView
  	style={{height: '100%'}}
  	projection="mercator"
  	styleURL="mapbox://styles/mapbox/standard"
  >
  	<MarkerView
  		coordinate={[4.3572, 50.8477]}
  	>
  			<View
				style={{
					width: 40,
					height: 40,
					backgroundColor: "red"
				}}
			></View>
  	</MarkerView>
  </MapView>
    );
  }
}

Observed behavior and steps to reproduce

You'll see when the marker (size 40px), is 20px over the edge of the screen, the marker disappears. This is extra visible when you play with custom anchor points. When you play with a custom anchor (eg 1,1), you'll see the marker disappearing way too soon (a marker with size of 40px will already disappear when its 40px away from the edge)

Expected behavior

The map should remove the marker from the view when the marker is 100% outside of bounds as an optimization. When the marker is still halfway visible, it should not disappear. This avoids pop-in/pop-uit effects

So basically it's an upstream feature we don't have much control over it. You can try to render an 1px by 1px view annotation with a children that's bigger than the parent - render outside parent. It might or might not work. Overlap control will not work for sure.

I'm closing this now as unlikely to change, feel free to add feature requests to upstream iOS and android repos
