> zoom issue

[MitsuraIvan]

map shows blank page on any zoom value near to x.9999999999999999, because tiles are drawn outside map.

1. enable rendering of the bound boxes
   void main() async {
   debugPaintSizeEnabled = true;
   //your code
   }
2. open map. notice, that the tile bounding boxes are drawing over map
3. using touchpad/phone zoom to x.9999999999 one mm away from going up a zoom value
4. no tiles are drawn over map, map is empty.

the issue is clearly visible when going up/down with touchpad all the time, like a dead frame.
