Packaging that involves a compilation process causes custom icons to not show in the taskbar on Windows in Binary

Packaging that involves a comilation process in the Binary editor causes custom Windows icons to be ignored in packaged games. This could either be seen in a Code project or in a Blueprint Only project that includes custom code plugins (which will also trigger a compilation process upon packaging)

Regression?: Yes
This does not occur in 4.20

This may be related to or caused by the fix for [Link Removed]

1. Create a new code project in a Binary editor (this does not occur in a Source built editor)
2. In Edit > Project Settings > Platform > Windows, change the Game Icon to a custom icon
3. Package the project for Win64 Development
4. Note that the .exe file has your icon shown
5. Run the .exe for the packaged project
   Result: The default UE4 logo is shown in the Taskbar
   Expected: The custom icon is shown in the Taskbar
