Currently, If Page A refers to Block β contained in Page B, Page A will appear in Block β’s Linked Reference
panel rather than Page B’s, so that there will be no link between Page A and Page B in Page graph, which results in a kind of information loss.
Page A citing Page B’s blocks, imho, implies some sort of relationship between this two pages, and such a relationship should be shown in both the “Linked Reference” panel and the Page graph.
