Don't skip previous chapter when "Skip chapters marked as read" is enabled

[dthunes]

Describe your suggested feature

When scrolling up, the previous chapter should load, even if it's marked as read and "Skip chapters marked as read" is enabled under Settings > Reader.

When "Skip chapters marked as read" is enabled it's not convenient to refresh my memories with the last few pages of the last chapter. There is also a bug that can quickly scroll multiple pages, even through a chapter break. "Skip chapters marked as read" will lock the chapter as soon as it's marked as read, even without existing the reader.
