IntelliSense stops working when Copilot Editor Mode is enabled

[rafaelbarross]

Does this issue occur when all extensions are disabled?: No

VS Code Version: 1.99.3 (user setup)

OS Version: Windows 11 (10.0.22621)

Steps to Reproduce:
Enable GitHub Copilot extension.

Activate Copilot Editor Mode.

Try to use IntelliSense (e.g. autocomplete, suggestions, hover info).

Expected Behavior:
IntelliSense should work normally, offering code suggestions and other features even when Copilot Editor Mode is active.

Actual Behavior:
When Copilot Editor Mode is active, IntelliSense stops working — no code suggestions, no hover documentation, and no parameter hints.

This negatively impacts productivity as Copilot and IntelliSense are often used together to speed up development.

Can reproduce. Only happens in JS/TS files as far as I've noticed, and Deno's LSP works, so I think it's related to in-built JS/TS LSP?

Yes, I'm using TS.

I haven't tested it with any other language. So you're right!

@rafaelbarross could you please provide additional steps on how to reproduce this. I tried it using the edit mode inside the chat panel and TS features still work for me.
