Copy Reference option is broken on Linux

Attempting to use the Copy Reference option from an asset's right click menu on Linux will clear the clipboard of any current value, but does not copy the reference back to the clipboard. This makes the option unusable since after copying the reference, there is nothing to paste.

1. Open UE4 Editor (any project)
2. Add blueprint to project based on Actor (MyActor)
3. Right click MyActor in content browser and select Copy Reference
4. Right click in a text field

Result:
Paste option is gray'ed out & Ctrl+V has no effect

Expected:
User is able to paste the copied reference using any Paste method/shortcut
