Current behavior

This works

Code.Fragment.surround_context("Collectable.into(a)", {1, 3})    
%{begin: {1, 1}, context: {:alias, ~c"Collectable"}, end: {1, 12}}

This also works

Code.Fragment.surround_context("Collectable.Map", {1, 3})        
%{begin: {1, 1}, context: {:alias, ~c"Collectable.Map"}, end: {1, 16}}

but this returns :none

Code.Fragment.surround_context("Collectable.Map.into(a)", {1, 3})
:none

Expected behavior

%{begin: {1, 1}, context: {:alias, ~c"Collectable.Map"}, end: {1, 16}}
