Actually, I see more:

https://koschei.fedoraproject.org/affected-by/bash?epoch1=0&version1=...

e.g. pytest:

         child.expect("Pdb")
>        assert "\r\n'i=0.'\r\n" in
> child.before.decode("utf8") 
E       assert
"\r\n'i=0.'\r\n" in ") 'i=%i.' % 
i\r\n\x1b[?2004l\r'i=0.'\r\n\x1b[?2004h("
E        +  where ") 'i=%i.' %
i\r\n\x1b[?2004l\r'i=0.'\r\n\x1b[?2004h(" = 
<built-in method decode of bytes object at 0x3ff4c3ff3f0>('utf8')
E        +    where <built-in method decode of bytes object at 0x3ff4c3ff3f0> = 
b") 'i=%i.' % i\r\n\x1b[?2004l\r'i=0.'\r\n\x1b[?2004h(".decode
E        +      where b") 'i=%i.' %
i\r\n\x1b[?2004l\r'i=0.'\r\n\x1b[?2004h(" = 
<pexpect.pty_spawn.spawn object at 0x3ff4c3e1b80>.before

E       AssertionError: assert '\r\nENTERING RECURSIVE DEBUGGER\r\n' in 
'\r\n\x1b[?2004hdebug set_trace()\r\n\x1b[?2004l\rENTERING RECURSIVE

or python-pexpect:

>        assert res.strip() == '11' 
E      
AssertionError: assert '\x1b[?2004l\...\n\x1b[?2004h' == '11'
E         - 11
E         + [?2004l
E         + 11
E         + [?2004h

And more...

Also ccing devel list for help.
