The first issue with the line not being cleared is indeed fixed.

The second one with incorrect history entry output position after e.g.
End is pressed is unfortunately still there:

test@sid-bash:~$ echo $0
test@sid-bash:~$ PS1='\[\e]0;тестоваястрока\a\]test prompt\$ '
test prompt$ echo hello world
hello world
test prompt$ 

# Press C-r, type 'he' and press End
# Result:

test prompt$rld
           ^------ cursor is here
