 Tested on Windows 10x64, with a recent build from master HEAD
 (2026.1.1git).

 On the ScummVM launcher, when trying to navigate a list of added games
 that is multiple "pages" long, using the keyboard keys, there are the
 following issues that I could spot:
 - Using PgDn at the top of the list requires two presses to start moving
 to the next page. A similar behavior is observed when at the bottom of the
 list, requiring two presses of PgUp to start moving to the next page
 upwards. Also, this might not be limited to being at the top or bottom of
 the list. An outstanding example of this issue is to focus on the list,
 when about at the middle of its listings, then alternate pressing PgDn and
 PgUp. The listview will maybe shift once, then won't "react" to the
 alternate pressing of PgDn and PgUp.
 - After moving to a "page" different than the one with the currently
 selected game, pressing Up or Down keys make the selected game "jumps" to
 the top of the page, instead of switching to the page with current
 selection.

 These may be regressions since the integration of multi-select
 functionality in the list view.

 There could be other related issues/regressions so we could gather them in
 this bug report to track their resolution.
