We don't know how many log lines wrap, so scrolling the log with page up and down with wrapped lines would skip lines, and those are also already bound to history navigation.
This therefore only implements scrolling of one item at a time. While not perfect because when the item is wrapped it scrolls multiple lines, it is usable.
The number of log lines kept in memory is increased from 100 to 1000.
Closes #14718.
