Run Python File in Terminal doesn't stop existing run #12185

When I click the "Run Python File in Terminal" button, if a program is already running, it will not be interrupted; instead it will just try to paste the python command into the terminal. This also may be interpreted as input to the already running command.

Expected behaviour

An existing script run will be killed and the new script run will execute in the terminal

Actual behaviour

The script will continue running and the new run command is pasted as keyboard input

Steps to reproduce:

1. Open python script which doesn't terminate immediately
2. Click "Run Python File in Terminal"
3. Modify script
4. Click "Run Python File in Terminal" again
5. The original version keeps running
