config(inline): show next session if only both sessino ids are the same

[Will-ShaoHua]

Problem

Followup of #6419

Team decides to only show a subset of prefetched session instead of all as it's too intrusive experience.

Solution

Only display prefetched sessions when the session ids are identical to the very first one.
