ArcMap: When selecting a coordinate that has identical coordinates in the list, the point is not highlighted on the map

[lfunkhouser]

1. Add several points to the map using the Map Point Tool.
2. Add 4 points by entering in 45 45 4x.
3. Enable the Select Point Tool in the Input section.
4. Click on the map to select one of the points added using the Map Point Tool.
5. Result: a green outline indicating the point is selected and the coordinate is highlighted in the List.
6. Click on the map to select the point(s) at 45 45.

Result: the first coordinate added at that location is selected but only the coordinate is highlighted in the List. The point(s) do not appear to have a green outline around them indicating they have been selected in the map.

The selection is not adding an outline to the outside of the symbol, so the selection is hidden underneath the other points at that location.

Another method to identify the selection is on top of the symbol instead of outside the symbol

1. Selecting the first of the identical coordinates in the list shows the highlight on the map because it was the last placed, so it is on top of all the other coordinates.
2. Selecting any of the other identical coordinates in the list will not show the highlight because they are under the top coordinate.

Expected behavior All points at the location of 45 45 would have a green outline indicating they have been selected. Green outline would be on the edge/outside of the symbol not covering up the current symbol.

Going to verify this isn't an issue in ArcGIS Pro
