Read progress is not continuous for this article even when toggled auto

trying to reproducing it. it seems due to marking this block unread manually

in the newest version, open the article again(with auto toggled on) and scrolling passed the block manually marked unread, will mark it read again.

but if you mark unread block, and scrolling passed the block again with auto toggled on, it won’t be marked read.

results of these two condition seems conflicted.

In the latest version, open the article again will auto scroll to a farther position under the unread block. if auto toggled, this will make the unread block read
