Bug #21094: Module#set_temporary_name does not affect a name of a nested module

Wondering whether it's intentional and correct behaviour:

m = Module.new
m::N = Module.new
p m::N.name # => "#<Module:0x000000010d0a00b0>::N"

m.set_temporary_name("foo")
p m::N.name # => "#<Module:0x000000010d0a00b0>::N"

I would expect that setting foo as a temporary name changes m::N.name to foo::N.

This seems like a bug to me because if you set the temp name before creating N it works as you expected. Opened a PR https://github.com/ruby/ruby/pull/12658
