Error in type normalization

[jakobnissen]

Example:

julia> isequal(Tuple{Union{Base.KeySet{Symbol, Dict{Symbol, Any}}, Set{Symbol}}, Int64})
ERROR: TypeError: in new, expected Union, got Type{Tuple{Union{Base.KeySet{Symbol, Dict{Symbol, Any}}, Set{Symbol}}, Int64}}

It looks like the type is transformed from a tuple of unions to a union of tuples INSIDE the constructor of Fix2, after which there is a type mismatch. Not sure how that works.

May be same issue as #35661, but unlike in that example, this happens with concrete types.

This appears to be fixed om master - closing
