Symbols defined in scripts included via `Base.include(::Module, ::String)` don't show up in `names` anymore

Julia v1.11:

julia> function main()
           m = Module(:MyModule)
           module_content = """
               f() = nothing
               """

           mktempdir() do dir
               filename = joinpath(dir, module_content)
               write(filename, module_content)
               Base.include(m, filename)
           end

           return names(m, all=true, imported=true)
       end
main (generic function with 1 method)

julia> main()
3-element Vector{Symbol}:
 Symbol("#f")
 :MyModule
 :f

Julia v1.12:

julia> function main()
           m = Module(:MyModule)
           module_content = """
               f() = nothing
               """

           mktempdir() do dir
               filename = joinpath(dir, module_content)
               write(filename, module_content)
               Base.include(m, filename)
           end

           return names(m, all=true, imported=true)
       end
main (generic function with 1 method)

julia> main()
1-element Vector{Symbol}:
 :MyModule

Notably, this breaks the script used for Julia in Compiler Explorer (the names call now only returns the module name). I'm happy to adapt the script if this isn't considered a bug, but I'd need instructions for how to adapt this.

@vchuravy pointed out that

Base.invokelatest(names, m; all=true, imported=true)

should give the same answer in both v1.12 and v1.11, and that gives me a hint of how to adapt the Compiler Explorer script.

@vtjnash can you clarify? was there a discussion somewhere about making this change? Also, is it in news?

This is the whole binding participate in world age feature for 1.12. #58297, but maybe should be extended to mention this new behavior.
