Links provided by @which do not work for some functions

[4lrdyD]

In previous versions of Julia and IJulia, the links provided by @which opened a page with the corresponding code on github. Now, in the current version, the macro provides the link, however, it doesn't open any page for some especific functions, for example:

a=sparse(rand(10));
b=a;
@which a+b

Result:
+(x::SparseArrays.AbstractSparseArray{Tv,Ti,1} where Ti where Tv, y::SparseArrays.AbstractSparseArray{Tv,Ti,1} where Ti where Tv) in SparseArrays at C:\cygwin\home\Administrator\buildbot\worker\package_win64\build\usr\share\julia\stdlib\v1.1\SparseArrays\src\sparsevector.jl:1292

By clicking on the link, it doesn't redirect to the desired page.

This is JuliaLang/julia#31084, not an IJulia bug.
