==== Context
Eventually we want to deploy to wikis where the `ReferenceTooltips` gadget is enabled by default. We want to understand how that Gadget works in these situations and if we can suggest changes to allow compatibility.
Italian Wikipedia which is on our upcoming rollout list uses the en.wiki version of Reference ToolTips. This wiki is important for getting insights on how wikis using sfn-like templates will use Sub-referencing.
See here:

==== Task
[x] Test `ReferenceTooltips` with sub-refs
[x] Add the gadget to our docker-dev environment.
[x] For review: https://gitlab.com/wmde/technical-wishes/docker-dev/-/merge_requests/192
[x] Try to patch the gadget to support sub-refs ( similar to how it's working for ReferencePreviews )
[] Communicate the code change with the gadget maintainer(s), also via TechNews
