Collaborator saving removes uncommited whitespace for collaborator cursors when auto format on save

[AndreasBackx]

Product and Version [VS/VSCode]: 1.24.1
OS Version [macOS/Windows]: Linux
Live Share Extension Version: 0.3.295
Target Platform or Language [e.g. Node.js]: irrelevant

Steps to Reproduce / Scenario:

1. Start a collaboration session.
2. Let someone else join the session.
3. Place your cursor on a different line than the "guest" and indent some.
4. Tell the other user to save the file, triggering VS Code to remove the whitespace.
5. The whitespace is removed on the line I was currently working on (when it was empty).

When working with someone and you're starting on a new line and the indentation is suddenly gone because the other user saved the project (out of habit) it's a little bit frustrating.

This also happens to the guest when the host saves.

This is when you have the editor.formatOnSave setting set to true, on the host, correct?

[AndreasBackx]

@grork that is correct. Unsure whether the collaborator had it.

@grork This may be related to #552, which could be caused by “editor.formatOnType”

Sounds like yall already have a good grasp on this issue and I see its on the roadmap, but figured I would add my info in case it is helpful. I was trying to teach a friend over LiveShare last night when this issue caused us to abandon our LiveShare session in favor of regular screen share.

Seems like the easy work around is turning off formatting which I'll do tonight when we try again.

Relevant settings:

Let me know if there is anything else I can provide to help!
