Monaco Editor Playground Code

const originalModel = monaco.editor.createModel(
    '\n\nhello world\n\n\n\nTesting\n\nTest',
    'text/plain'
);
const modifiedModel = monaco.editor.createModel(
    'Hello World!\n\n\n\nTesting\n\nHi',
    'text/plain'
);

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

Reproduction Steps

Use a diffEditor with glyphMargin: true in v0.48.0 or later

Actual (Problematic) Behavior

v0.48.0 - the diff glyphs do not render alongside each diff. Instead they are all at the top of the gutter.

Expected Behavior

v0.47.0 correctly shows the glyphs alongside each diff
