On mobile devices the map view becomes unresponsive to click or double click for a second visit or thereafter

When the map view is visited the **second time** the **view** becomes unresponsive to clicks, double clicks or taps. This may be related to #14 Double tap on touchpad doesn't trigger zoom.

To reproduce,

1. load the app on a mobile device (or chrome responsive view)
2. click on a list item to navigate to the map view
3. click or double click or tap....view/map responses.
4. go back to the list view and click some other item or simply navigate back to the map view
5. the view stops responding

I have reverted back to JS API version 4.11 and this issue goes away but want to use the latest and greatest JS API (>= 4.14). It also fails with 4.15 as well.


Any help is appreciated. Thanks.
