I couldn’t find the link to/from post #19 but this behavior should already exist. If you are navigating from one post to another, it goes through the same “jump to post” logic that using the progress bar does. If it doesn’t, I’ve missed a weird case and should fix it!
Can you tell me exactly what link to click to demonstrate this?
Bear in mind if the post segment does not exist in memory you will see a Loading… indicator first.
