Summary: Fixes T6731. I don't really understand the intent behind the two view classes here, but to get this to work I need to pass yet more data to the lower-level class.

Test Plan: Viewed a task with many comments. Clicked "show older". Quoted everything I could. Verified for each quote that it quoted correctly, inlcuding linking to the prior transaction.
