For the record.
Bibliography entries do not receive a specific character style like note anchors or hyperlinks. Consequently, user has to painfully hunt for the entries and apply manually some style. There is a high risk to forget entries as is the case with any manual process.
I fully support an enhancement to mark up bibliographic entries with a dedicated character style.
@Tommy62: your enhancement request is now filed. But this is FOSS based on volunteers development. There is already a considerable backlog of bugs, some of which really annoying. So don’t expect a quick implementation. However, you are allowed to hope.
