Problem When a user loads their dashboard https://www.wikibase.cloud/dashboard and they have Wikis already, they might see an empty list and thus wonder where their Wikis are gone.

whereas the user expects their Wikis to show like this:

This happens because the list of Wikis is being retrieved and during the retrieval, the list is empty (It is a bit hard to reproduce, as it is not just dependent on connection speed)

Solution: Show a loading indicator where the list of Wikis would be. Ideally, also show "No wikis" (or so) when there are actually no wikis so that no matter what the result of the data retrieval is, the loading indicator is replaced with something meaningful.
