Describe the bug
Can't create std::packaged_task with lambda.

I receive compilation error:

call to implicitly-deleted copy constructor of '(lambda at main.cpp)'

Command-line test case
STL version (git commit or Visual Studio version): Visual Studio 2019 16.3.9

https://godbolt.org/z/2CysfN

Expected behavior
Should work like gcc linux/clang linux or mingw64-gcc and mingw64-clang
