Updated packages
SUMMARY
Some apps like Chrome/Thorium is not aware that my cursor is hovering over it,
and can't drag and drop in apps such as dolphin. (works normally when using a
mouse)
This issue cropped up when upgrading to Plasma 6.3.0 which is supposed to be
somewhat of a tablet overhaul, so I guess it is pretty natural to suspect it.
After rolling back to a previous snapshot of root, my tablet worked on Chrome
again.
STEPS TO REPRODUCE
1. Upgrade whole rolling release to Plasma 6.3.0 and related packages to 6.3.0
2. Use wayland
3. Open Chrome & Drag and drop in apps like Dolphin
OBSERVED RESULT
Chrome/Thorium is not aware that my cursor is hovering over it or that I’m
clicking on it with my tablet and shows a plus cursor or sometimes the normal
pointer.
Sometimes after focusing Chrome the tablet stops being able to click on
anything (even switching to other apps).
(Focus chrome, then alt tab to dolphin for example, dolphin does not recognize
the tablet like in Chrome.) (Sometimes the plus cursor also shows up on other
applications when this happens)
Until the new focused application is clicked with a mouse or trackpad.
I also noticed that I can't drag and drop in apps like dolphin with the tablet,
it only selects it.
EXPECTED RESULT
Tablet works normally like a mouse in all applications.

I have tried upgrading the packages above and my tablet still works fine in
Chrome.
I have attached pacman.trimmed.log which lists all the packages I've updated.
They are the packages that may have caused the breakage.
