Monaco Editor Playground Code

const originalModel = monaco.editor.createModel(
	/* set from `originalModel`: */ `test
first deleted line
second deleted line
third deleted line
test end
`
);
const modifiedModel = monaco.editor.createModel(
	/* set from `modifiedModel`: */ `test
test end
`,
	"text/plain"
);

const diffEditor = monaco.editor.createDiffEditor(
	document.getElementById("container"),
	{
		automaticLayout: true,
		renderSideBySide: false,
	}
);
diffEditor.setModel({
	original: originalModel,
	modified: modifiedModel,
});

Reproduction Steps

1. Ensure that the diff is not rendered side by side.
2. Click on the text "first deleted line" in the diff.
3. When the menu appears, click "Copy deleted line (2)"
4. Paste the text you copied somewhere.

Actual (Problematic) Behavior

The editor copies the wrong line to the clipboard. Selecting the line that reads "first deleted line" will instead copy "second deleted line". (Similarly, selecting the second deleted line will copy "third deleted line")

Expected Behavior

The editor should copy the line the user selects. In the example above, I would expect "first deleted line" to be copied to the clipboard.
