It is possible to view past comments of a thread, but not possible to view any of the subsequent comments.

Given the feed below:

A-1
A-2
B-1
B-2
A-3

"A" and "B" are threads, and the numbers are the sequence of comments.

If someone shares the link of "A-2", I'm able to see that "A-2" is a comment on "A-1", but I can't see "A-3". This suggestion is a request to enable me to see "A-1" AND "A-3" whenever someone shares the link of "A-2"
