Bug report

Bug description:

Below, the first occurrence of "copyright" was pasted in. The second occurrence was pulled from history using up-arrow. Note that the former doesn't print the result.

~/cpython$ ./python.exe 
Python 3.14.0a0 (heads/main:7e894c2f38f, May 11 2024, 14:54:01) [Clang 15.0.0 (clang-1500.1.0.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> "copyright"
>>> "copyright"
'copyright'
>>> 

Worse, even if any part of a line was pasted in, it seems the result isn't printed.

It's the same in 3.13b1.

Sorry about that. I searched but didn't find that issue somehow.
