   Thanks for porting the carriage return handling form the classic UI!
   
   Just a quick note. The current implementation replaces the whole line with 
only the last part after `\r`, so something like `Hello World\rDone` ends up as 
`Done`.
   But in most REPLs or terminal-like environments, `\r` usually acts as a 
partial overwrite. So the expected output would be `Doneo World`, since only 
the beginning of the line gets overwritten and the rest stays as is.
   
   Since interpreters are writing output with that behavior in mind, I think it 
might make sense to handle it that way in the new UI too. What do you think?
