[BUG] [Reopened] App crash with consecutive downloaded chapters browsing/navigating

[Ivanmatthew]

Reopening of issue #789 Original message: Describe the bug When reading or skipping chapters, the app crashes

To Reproduce

Download ~5 chapters of the same manga Open the first chapter Press the next chapter button a few times Scroll down a bit, you’ll see the last chapter’s image phasing into the current chapter’s image. At this point it crashes. Expected behaviour The next chapter to have properly loaded and the previous chapter to have properly be unloaded

App Version v0.8.6-r2

P.S. Issue is solved for non-downloaded chapters, but still persists on downloaded chapters. The debounce/cooldown you put on navigating to next/previous chapters takes too long to block navigation that it will still allow for original reproduction steps to take place.

Most likely solvable by checking the state of the unloading process for last chapter(?)
