Description

Describe the bug If a webtoon isn't long enough to require a scrollbar be generated, you will not be able to turn to scrollwheel to go to the next / previous chapters

To Reproduce Steps to reproduce the behavior:

  1. Open a very short webtoon and make sure there isn't a scrollbar
  2. Switch the reading mode to continuous scrolling
  3. Scroll in either direction
  4. The "Scroll to next / previous chapter" message should not appear

Expected behavior You should always be able to scroll to go to the next / previous page, no matter the chapter length.

Desktop (please complete the following information):

  • OS: Docker
  • Browser Firefox
  • Version 0.5.6.29

Additional context Here's a test file. Copy the images to increase the page length Kavita Testing Ch. 1.zip

Research direction
The bug is in the continuous scrolling mode. The fix likely involves modifying the scroll event handler in the reader component. Look for files related to reading mode or scroll logic. Ensure that chapter navigation triggers even when the content does not overflow the viewport. Review the comments on the issue for any additional context.
