Bug description

When trying to remove a marker from the map using setMap(null) and set the object and all known references to null, marker stays in memory.

Steps to reproduce

You can reproduce it with your own example:
https://jsfiddle.net/gh/get/library/pure/googlemaps/js-samples/tree/master/dist/samples/marker-remove/jsfiddle

1. open the url
2. create a heap memory dump in developer tools
3. search for "_.wh". There are four objects
4. click on "delete markers" in jsfiddle
5. click on garbage collector in developer tools
6. create a new heap memory dump in developer tools
7. search for "_.wh". There should be one less, but still four availble.
