Monaco Editor Playground Code

monaco.editor.create(document.getElementById('container'), {
  value: "function hello() {\n\talert('Hello world!');\n}",
  language: 'javascript',
  inlineSuggest: {
      enabled: true,
  }
});
 
class InlineCompleter {
provideInlineCompletions() {
      return {items: [{insertText: '11111'}, {insertText: '22222'}]};
  }
  freeInlineCompletions() {}
}
monaco.languages.registerInlineCompletionsProvider('javascript', new InlineCompleter());

Reproduction Steps

1. Trigger the inline completions provider
2. Hover over suggested text so that action bar shows up
3. Click three-dot menu in action bar
4. Notice there are no styles applied to the three-dot menu (bug)

Actual (Problematic) Behavior

The three-dot menu does not have any styling applied to it. It looks like it is added to the DOM outside of the .monaco-editor context and therefore thinks that none of the styling variables exist. The result is that the menu is unstyled.

Expected Behavior

The three-dot menu for inline completions action bar should have styling applied to it.

Additional Context

No response

Open the linked Monaco Editor Playground and reproduce the unstyled three-dot menu in the inline completions action bar. Trace how that menu is styled relative to the .monaco-editor context; done means the menu has the expected styling in the supplied reproduction.
