Report: Linked entities and email field

[PGI]

Hello,
When you create a link between opportunity and lead. If you create a list report based on opportunities, it is possible to access the prospects' fields but not their email.
Does anyone have a solution to this problem?
Thank you
PS: I recreated this same scenario on the demo.

Hello
For reports are available only simple (not related) fields for related records.
