Chrome would only drop into windows supporting v5 of the XDND spec, resolve by bumping the version and no other changes. From looking into the changes between v3 & v5 they mainly relate to dragging files between windows & dragging onto the root window. Since Blender does neither, bump the version to allow dragging links from google-chrome.
