Monaco Editor Playground Code

const originalModel = monaco.editor.createModel(
	/* set from `originalModel`: */ `no red square for this line in the inline view
(uncomment \`renderSideBySide: false\`)`,
	"text/plain"
);
const modifiedModel = monaco.editor.createModel(
	/* set from `modifiedModel`: */ `green square for this line works in both cases`,
	"text/plain"
);

const diffEditor = monaco.editor.createDiffEditor(
	document.getElementById("container"),
	{
		originalEditable: true,
		automaticLayout: true,
        glyphMargin: true,
        renderMarginRevertIcon: false,

        // renderSideBySide: false,
	}
);
diffEditor.setModel({
	original: originalModel,
	modified: modifiedModel,
});
for (const [editor, cls] of [
    [diffEditor.getOriginalEditor(), 'original-decoration'],
    [diffEditor.getModifiedEditor(), 'modified-decoration'],
]) {
    editor.createDecorationsCollection([
        {
            range: new monaco.Range(1, 1, 1, 1),
            options: {
                glyphMarginClassName: cls,
            },
        },
    ]);
}

Reproduction Steps

Uncomment renderSideBySide: false.

Actual (Problematic) Behavior

The red square, which was present in the side-by-side view, disappears in the inline view.

Expected Behavior

The decorations should be rendered in both views.

Additional Context

It worked in v0.44.0.

I'm using createDecorationsCollection in the example, but the same happens with addGlyphMarginWidget.

Start with the linked Monaco Editor Playground example and run it with renderSideBySide: false, comparing the original and modified glyph decorations. Trace the createDiffEditor inline rendering path, including createDecorationsCollection and addGlyphMarginWidget, and verify that decorations on deleted lines render in both inline and side-by-side views without regressing the v0.44.0 behavior.
