**User Story**
As a user reading an article in mobile view, when I click a sub-ref footnote marker, I want to be able to see the full bibliographic information, incl. sub-reference information, from within the article so that I can be informed about the precise details of the source.
**Solution**

So for each subref, we show the subref number, the full main ref content, and the full subref content.
Changes compared to the reference preview on mobile for //main refs without subrefs//:
* The number in front of the main reference should be the subref number -> [1.1] instead of [1]
* The subreference should be displayed on a new line underneath the main reference content. No additional padding or spacing in between the main & subref is required.
**Current status quo:**
For ReferencePreview in Reader Mode in mobile view, the main ref is missing currently:

The ContextItem for subrefs in VE covers a large part of the screen but for now is acceptable and does not need changes.
