If a qualifier label is not available in a user's language (as defined by their language fallback chain), we are displaying the wb-language-fallback-indicator markup that is returned from Wikibase. This is a superscript element which displays the language that the label being shown is written in.
This behavior should also be applied to the following UI elements:
- Top-level property for a given StatementsPanel
- Entity label for a given statement within this panel (the ItemWidget element)
