https://github.com/void-linux/void-packages/issues/34442

Description:
* xuname:
  `Void 5.15.1 x86_64 AuthenticAMD uptodate hold rrrmFFFFFFFFFFF`
* package:  
  `rxvt-unicode-9.30_1`

### Expected behavior

Was pasting without verify warning until a week or few ago

### Actual behavior

![paste_verify](https://user-images.githubusercontent.com/8009811/145402368-d1e5de68-9c21-4101-97d2-73c066d6d4cf.png)

Putting `URxvt.perl-ext-common: default` in .Xdefaults or .Xresources worked for maybe a day, now it does not, but I don't think urxvt updated.

### Steps to reproduce the behavior

 - highlight text somewhere
 - Open a terminal
 - Middle mouse click to paste in terminal
