In case two pages were displayed with different dimensions, the bigger page might take up more than 50% of the screen.
In this case the bigger page got limited to 50% which caused in to unintentionally get reduced in size
There was an issue where one had to click twice at the end of a chapter in the "double page mode" to get to the chapter transition page.
This was caused due to setting the "primary page index" as the "current page index" and thus, when opening the next page, it got changed to the "secondary page index". However, this page was already visible and therefore, there was no visual change.
