Actual (Problematic) Behavior

I'm getting the following console error when closing a modal containing a DiffEditor:

Error: AbstractContextKeyService has been disposed
    at ScopedContextKeyService.contextMatchesRules (contextKeyService.js:241:19)
    at MenuInfo_1.createActionGroups (menuService.js:222:45)
    at MenuImpl.getActions (menuService.js:362:31)
    at FromEventObservable._getValue (gutterFeature.js:47:86)

    at DebounceEmitter.resume (event.js:1001:27)
    at event.js:1035:22
    at errors.js:15:27

Editor Options:

{
  automaticLayout: true,
  find: {
    addExtraSpaceOnTop: false,
  },
  glyphMargin: true,
  readOnly: true,
  scrollbar: {
    alwaysConsumeMouseWheel: false,
  },
  scrollBeyondLastLine: false,
  quickSuggestions: true,
}

Expected Behavior

No console error.

Additional Context

This error only occurs when renderGutterMenu: true (which is the default). The error is not present in versions <= 0.47.0.
