[This issue is more like a future request]

Steps to reproduce:
1. Open attached project.
2. In the "Project" window select all the assets (render textures) that are located inside of the folder named "New Folder" (hold "Shift" key while selecting).
3. Right click on one of the selected assets.
4. Select "Show in Explorer" option.

Actual result:
The Editor opens as much new explorer windows as assets selected despite the fact that all of these assets are located in the same place.

Expected result:
The Editor should open only one explorer window when all selected assets are located in the same place.

Reproduced with:
5.1.0f3, 5.2.4f1, 5.3.4f1, 5.4.0b18.
