Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `function hdsdello() {
	alert('Hello world!');
}
func`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "javascript",
	automaticLayout: true,
	fixedOverflowWidgets: true
});

<div style="transform: translate(84px, 165px); height: 100%;">
    <div id="container" style="height: 100%"></div>
</div>

Reproduction Steps

No response

Actual (Problematic) Behavior

Suggestion widget shows at a wrong location (left is correct, top is incorrect) when fixedOverflowWidgets is true.

Old issue https://github.com/microsoft/monaco-editor/issues/2503.

Expected Behavior

I expect it to work in the same way as when fixedOverflowWidgets is true

Additional Context

No response

Start with the linked Monaco Editor Playground reproduction and its create call using fixedOverflowWidgets: true, then compare the suggestion widget's position inside the transformed container with the reported screenshots. Trace the overflow-widget positioning path and verify that the widget's top and left coordinates are correct when Monaco is hosted in a Fluent Callout; done means the reproduced placement matches the expected behavior.
