Pop not working on Ubuntu 24.04

Regarding [push/pop](https://github.com/hluk/CopyQ/issues/597#issuecomment-1728895131) that you've helpfully posted [here](https://github.com/hluk/copyq-commands/blob/master/Global/README.md#pushpop-items).

On Ubuntu 22.04, while the push/pop commands are pushing onto the stack and removing from the stack, they are failing to paste, and this is true for plain text. I have tried using control-alt-c/v and control-command-c/v, copying and pasting from `gedit`. In both cases, it's the same issue.
