BUG: Can't compile due to duplicated arguments for linker command

Hi
I attached simple project replicating the issue.

Code added in "Shared Items Project" (VS built in, I did't check the Visual Micro one) results in "multiple definition of xxx" error. This happens because linker command has duplicated arguments for "xxx.cpp.o" file.

example command from attached project:
"C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avr-gcc" -w -Os -g -flto -fuse-linker-plugin -Wl,--gc-sections -mmcu=atmega328p -o " "SharedBug.cpp.o" "OkClass.cpp.o" "OkClass.cpp.o" "VM_DBG\VM_DBG.cpp.o" "VM_DBG\VM_mem_check_sam.cpp.o" "C:\Users\User\AppData\Local\Temp\VMBuilds\SharedBug\uno\Debug/core.a" "-LC:\Users\User\AppData\Local\Temp\VMBuilds\SharedBug\uno\Debug" -lm

As you can see the "OkClass.cpp.o" argument is duplicated. Issuing command without duplication works correctly.

software:
Microsoft Visual Studio Community 2019 Version 16.5.1
Visual Micro Version 2020.321.2 (and some earlier)
