Describe the bug / provide steps to reproduce it

1. Run the following commands:

git clone https://github.com/landaire/acceleration.git
git checkout dev
zed .

2. Open the stfs/Cargo.toml file
3. Attempt to insert a new dependency key (e.g. bytes = "1.6" on line 18)
4. Save the file
5. The key that was inserted will be removed, and a [patch.crates-io] section will be inserted
6. Removing any of the [patch.crates-io] content and saving the file will result in it being re-inserted

In the following video I am only inserting the bytes key, then deleting the [patch.crates-io] section and saving repeatedly. I'm not undoing anything or pasting content.
