Monaco Editor Playground Code

customElements.define(
	"code-view-monaco",
	class CodeViewMonaco extends HTMLElement {
		_monacoEditor;
		/** @type HTMLElement */
		_editor;

		constructor() {
			super();

			const shadowRoot = this.attachShadow({ mode: "open" });

			// Copy over editor styles
			const styles = document.querySelectorAll(
				"link[rel='stylesheet'][data-name^='vs/']"
			);
			for (const style of styles) {
				shadowRoot.appendChild(style.cloneNode(true));
			}

			const template = /** @type HTMLTemplateElement */ (
				document.getElementById("editor-template")
			);
			shadowRoot.appendChild(template.content.cloneNode(true));

			this._editor = shadowRoot.querySelector("#container");
			this._monacoEditor = monaco.editor.create(this._editor, {
				automaticLayout: true,
				language: "javascript",

				value: `function hello() {
	alert('Hello world!');
}`,
			});
		}
	}
);

Reproduction Steps

• select a piece of the text
• right click the selected text
• "Copy" ( or any other action)

Actual (Problematic) Behavior

the selected text is copied but loses the focus

Expected Behavior

it should do the same as an editor not in a shadow dom(e.g.: https://microsoft.github.io/monaco-editor/playground.html?source=v0.39.0#example-creating-the-editor-hello-world) and keep the focus.

Additional Context

I believe this issue is also making it impossible to use the "Paste" action in a shadow-dom, it loses the focus as soon as you open the context menu, making it impossible to go through this condition.
But I can't reproduce it in playground because "Paste" action doesn't work at all in playground https://github.com/microsoft/monaco-editor/issues/2264

Start with the linked Monaco Editor playground and the provided custom-element reproduction, then compare it with the non-shadow-DOM example. Reproduce the context-menu Copy action after selecting text, and verify that the editor retains focus afterward; also check whether the Paste action behaves consistently with the reported clipboard condition.
