This is not an issue specific to the Pager applet, this applies to pretty much everything related to Plasma. This also seems to have existed since Plasma 4.
Previous Bug Reports:
The issue is that when you disable the "Desktop navigation wraps around" option in System Settings -> Desktop Behavior -> Virtual Desktops -> Switching, KWin respects the decision but nothing in Plasma respects it.
Unfortunately, I could not find any setting in Plasma that respected this wrap disabling.
Steps to Reproduce:
1. Disable navigation wrap.
2. Mouse scroll on Pager widget or system desktop.
1. In the Pager widget, do a mouse-scroll on it and the desktop navigation wraps.
2. Using the Mouse-scroll on the desktop itself via the Desktop Settings -> Mouse Actions -> Vertical-Scroll = Switch Desktops the navigation continues to wrap.
Stop at the first and last desktops when this setting is disabled.
If you have shortcuts defined in KWin for switching desktops then those shortcuts respect the option of disabling the navigation wrap.
KWin Shortcuts I've Tested that Work as Expected:
Switch to Next Desktop
Switch to Previous Desktop
Switch One Desktop Up
Switch One Desktop Right
Switch One Desktop Down
Switch One Desktop Left
I am having this same problem, further more I noticed as of 5.7 upgrade to neon, it causes a kwin crash as well to break compositing. If I untick "Desktop navigation wraps around", and cause an infinite loop of the desktops, kwin does not crash.
Same as above to reproduce, but Mouse scroll causes kwin to crash as well.
Can reproduce this bug without crashing in:
OS: Netrunner Rolling
This setting is still ignored in Plasma 5.13.
KDE Plasma Version: 5.13.14
KDE Frameworks Version: 5.49.0

Implement option to toggle page navigation wraps around for pager plasmoid
This patch implement an option to disable navigation wraps around for the pager plasmoid, which potentially cause inconveniences for user who switch desktop using mouse wheel or touchpad scroll.
The patch is implemented since "Desktop navigation wraps around" option in "System Settings -> Desktop Behavior -> Virtual Desktops -> Switching" only affects keyboard shortcut mapping.
