To clarify, the problem is that any interpreter of escape sequences should be ignoring any OSC sequence it does not understand. |

Further resolves: #24422 Prevent keyboard interrupt for Mac and Linux when using Python3.13 Having Python3.13 as interpreter choice and then enabling shell integration where it is normally supported (we disabled temporarily for Python3.13 due to python/cpython#126131), lead to edge case. So although we don't override user's PS1 in Python side after checking Python3.13 is selected, we were not aware of this in typescript side, leading to wrongly using executeCommand inside Python terminal REPL (Python3.13 IDLE), instead of sendText.

Bug description:
VS Code has set of custom escape sequences that allow shell integration.
We have a custom pythonrc file that we set equal to user's PYTHONSTARTUP file and effectively override user's sys.ps1(this can be improved once we have the pre-exec hook mentioned in the related PR) This allows us to get features that VS Code shell integration offers.
With the new REPL that 3.13 offers, we have noticed that the cursor location is wrongly placed whenever REPL from Python3.13 is launched from our terminal. See:
After investigation we found out it is because Python3.13 is somehow handling our custom sequences such as
instead of ignoring them as it did in the previous versions of Python. This is what is leads to the wrong cursor location at the end. Removing these sequences brought back the cursor to the "right" position in terminal.
CPython should ignore these custom sequences instead of wrongly handling them.

coming soon (would appreciate advice on where to start digging in but I assume it is somewhere https://github.com/python/cpython/tree/main/Lib/_pyrepl)
