Inserting a new line when pasting

[abduazizR]

Hi

I believe my issue is similar to what has been demonstrated here https://stackoverflow.com/questions/53791340/vscode-copy-and-paste-1-line-without-newline-character-being-prepended

Briefly, when I paste a piece of code into my script, a new line is generated, which I don't want. I am not sure if setting positron to follow Rstudio customs should solve this, but in my case, it does not. Also, the suggestions on the StackOverflow question do not seem straightforward.

Could this be related to #4009, i.e. do you have editor.formatOnPaste enabled?

@abduazizR is this the behavior you are observing?

Are you working in R?

[abduazizR]

Yes and yes

I believe I am setting thisto true. I checked both the User and Default settings

I tested a variety of cases just to make sure it's working and that nothing was missed in this area. Please find the table above with what I've covered.
