Monaco Editor Playground Code

const value = `
const f = (a, b) => a + b;

const result = f(2, 5);
`;

const editor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "javascript",
});

monaco.languages.registerCodeActionProvider("javascript", {
	provideCodeActions: (model, range, context) => {
		return {
			actions: [
				{
					title: "Test action",
					edit: {
						edits: [
							{
								resource: model.uri,
								textEdit: {
									range: {startLineNumber: 1, startColumn: 1, endLineNumber: 1, endColumn: 1},
									text: "const ${1:test};",
									insertAsSnippet: true,

});

Reproduction Steps

try to use code action

Actual (Problematic) Behavior

code action insert text marked as snipped without modifying

Expected Behavior

code action insert text marked as snipped similar to CompletionProvider snippets

Additional Context

No response

Start with the linked Monaco Editor Playground and the provided CodeActionProvider reproduction. Compare the code-action text edit behavior with the expected CompletionProvider snippet behavior, then locate the relevant editor API implementation and tests; no specific files or tests are named in the issue. Done means applying the action inserts and activates the ${1:test} snippet rather than plain text.
