the precision of latitude and longitude in Mapview not accurate

[venkataraja705]

Describe the bug
i was using a dragresizable:rectangle where i was trying to get the lat and lon on all four directions
where the position is going little above when i try to get the lat&lon data using using the API mapview.get_latlon_at()

To Reproduce
Code example showing the issue:

KV=
<DragAndResizeLabel
id: drawresize
# Define the properties for the DragLabel
drag_rectangle: self.x, self.y, self.width, self.height
drag_timeout: 10000000
drag_distance: 0
draw_resize_border: True
resize_border_width: 2
resize_border_color: [1,0,0,1]

MDScreen:
name: "Configure"
MDBoxLayout:
orientation: "vertical"
MapView:
id: mapview
zoom: 12
MapMarkerPopup:
id: mapids

def get_coordinate(self):

point=self.root.ids.mapview.get_latlon_at(self.selection_rectangle.drag_rect_x , self.selection_rectangle.drag_rect_y )

top_left=self.root.ids.mapview.get_latlon_at(self.selection_rectangle.drag_rect_x+0 , self.selection_rectangle.drag_rect_y +self.selection_rectangle.drag_rect_height)

        bottom_right=self.root.ids.mapview.get_latlon_at(self.selection_rectangle.drag_rect_x+self.selection_rectangle.drag_rect_width,self.selection_rectangle.drag_rect_y)

top_right=self.root.ids.mapview.get_latlon_at(self.selection_rectangle.drag_rect_x+self.selection_rectangle.drag_rect_width , self.selection_rectangle.drag_rect_y +self.selection_rectangle.drag_rect_height-55)
