Thanks for the catch.

I noticed there is already an existing Release Notes entry for this issue from the earlier PR that partially addressed the generic lambda false positive before the issue was reopened. 

Since my patch fixes an additional missed case in dependent initializers, would you prefer updating that existing entry rather than adding a separate new note?
