URxvt.keysym.Shift-Control-V:   eval:paste_clipboard
URxvt.keysym.Mod4-Shift-v:      eval:paste_primary

no longer works in Debian 12 (and Ubuntu 22.04) if this bidi extension is loaded:

URxvt.perl-ext:                  bidi

Also, it does not depend on any settings; even with URxvt.bidi.enabled: 0 it is there;
copy/pasting with Ctrl-Alt-C/V works as before (if the above two upper uncommented lines in the code snippet are removed).
