Scrolling no longer works on desktop

STEPS TO REPRODUCE
1. Update to plasma 5.18.4? (at least that when the problem started happening)
2. Click on desktop
3. Use scroll wheel

EXPECTED RESULTS
Should switch between virtual desktops or do whatever "right click > configure desktop > mouse actions > vertical scroll" is set to do.

ACTUAL RESULTS
Nothing happens. 


OTHER NOTES
Change virtual desktop with any other mouse button works. 
Scrolling in other applications still works. 
Scrolling with mouse over virtual desktop icon on taskbar works.
"qdbus org.kde.KWin /KWin nextDesktop" command works as expected. (Should I be posting this report under kwin?)
~/.config/plasma-org.kde.plasma.desktop-appletsrc  has been reset to no effect.
Bug 413104 seems similar but no solution has been provided in that thread.


SOFTWARE/OS VERSIONS
OS: Manjaro
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.2

I created a temporary workaround with xbindkeys and xdotool.

In ~/.xbindkeysrc I added the lines:

"bash /home/username/scroll_down.sh"
    b:5
"bash /home/username/scroll_up.sh"
    b:4


The contents of the shell files are:

#!/bin/bash
eval $(xdotool getmouselocation --shell)
echo $WINDOW
name=$(xdotool getwindowname $WINDOW)
base="Desktop — Plasma"

if [ "$name" = "$base" ]; then
    echo succ
    qdbus org.kde.KWin /KWin nextDesktop
fi

With "nextDesktop" in the scroll_down/sh file and "previousDesktop" in the scroll_up.sh file.
The "qdbus" command could also be replaces with "xdotool set_desktop"

This assumes that you have two desktops stacked vertically.
Also there is no wrap around scrolling.

forgot to remove unnecessary "echo $WINDOW" and "echo succ"
