Claude 3.5 Sonnet doesn't write code directly to the editor in Edit mode

[TheWonderfulTartiflette]

Type: Bug

When using the Edit mode, Claude 3.5 Sonnet will write its code in the conversattion window rather than in the editor directly, like it would do if I was using the regular Chat mode

I'm not able to reproduce with the latest pre-release:

Here are my steps.

• Open SV Code on a folder that contains a file Hello.ts:

  
  function hello() {

}

- open chat edits view, make sure 'Hello.ts' is part of the working set
- select Claude 3.5 Sonnet as model
- ask `rename `hello` to `world``

Can you provide similar steps that show the problem?

Yes my bad, I forgot to say that this happens only sometimes. There doesn't seem to be history for the Copilot Edits, unlike Copilot Chat, so I can't give you exactly the prompt/answer it gave, but I think that this mainly happened when he needed to modify long files (mine was like 600 lines in python) btw how did you change the font in the copilot window ? i don't see where you change it

[TheWonderfulTartiflette]

I had this prompt where the issue occurred : Create a Python code, from start to finish, of a sort of “Paint” app, where the user can draw, fill, use shapes that he can resize, save the file, etc etc etc.. Make it as feature rich as possible. And make the UI not too bad

And for the first time, this occurred with o1-preview, whereas before this always occurred with Claude 3.5 Sonnet. Here is the screenshot

Thanks a lot. It's difficult to reproduce, but I saw it yesterday too. Likely the LLM uses a code block syntax that we don't expect (but the UI can rennder)
