"@ionic-native/core": "4.5.3",
"@ionic-native/google-maps": "^4.6.0",

Current behavior: When switching the tab in an Ionic app and then switching back to the tab with the map, the map sometimes disappears or does an unexpected animation from top left to bottom right. If you scroll in the other tab the map always disappears. After switching tabs a couple of times the map re-appears with the unexpected animation. See the following screen capture and demo code.

Expected behavior: The map not disappearing at least, best case no animation.
