After some exploring and fiddling around suddenly new entries were not loaded when using page up and down (or scrolling). I figured out a reproduction path:
- First use the search. Search for “Survivor” and hit Enter. Now it does a search on the whole dataset and it shows all results where “Survivor” is somewhere found.
- Now search again. Search for “Superman” and click the entry so it gets opened. On the left it shows the entries before and after “Superman”. Fine so far.
- Now if you scroll down (or use page down), new entries won’t be loaded that are coming after the last entry. However, if you keep scrolling up, it is loading entries at the start of the list.
- If you keep scrolling up. Like 10 times or something. You are removing entries from the bottom of the list too keep a smaller subset.
- If you now scroll down again, you can’t get back to “Superman” because it won’t scroll further down anymore.
When I found this, I was like: why is it not loading entries? Then I found the above reproduction path.
