--- Comment #3 from bugg.void@tutanota.com --- Yeah, it needs either null or space at the end of a matched token. In this case it has `:`. One way to fix it would be to allow other characters at the end but I'm not sure what other side effects would this introduce.
I'm also not sure why those devices are named likes this, I tested with Wacom Intuos Pro and XP-PEN Deco 03 but they both get generic 'xwayland-tablet' names. Another way to go around this problem would be to change device names somehow but I don't know if it's even possible.
