Paste mode in python 3.13 turns on in interactive help mode but doesn't work

[evle-zzz]

Bug report

Bug description:

Run python repl.
Enter "help" to start interactive help.
Prompt changes to "help>"
Press "F3" to enter paste mode. Prompt changes to "(paste)".
Paste something with multiple lines.
All the line ends get removed and an unusable line remains.

The issue is:

1. Why paste mode works within interactive help at all?
2. "(paste)" propmpt hides the fact that we are still within interactive help.

CPython versions tested on:

3.13
