Monaco perf improvement: Call updateOptions API only for props that have changed

[vivek1729]

We rely on the helpful updateOptions API on the editor instance to update a generic set of options. Since, this is tied to the componentDidUpdate lifecycle method, several calls to the underlying updateOptions API can lead to potentially unwanted dom manipulations.

We can consider adding some checks before calling this API so that we pass in only those props that have actually changed since the last update:

nteract/packages/monaco-editor/src/MonacoEditor.tsx

Lines 365 to 370 in d2088d0

 const monacoUpdateOptions: monaco.editor.IEditorOptions & monaco.editor.IGlobalEditorOptions = { readOnly: this.props.readOnly }; 
 if (theme) { 
   monacoUpdateOptions.theme = theme; 
 } 
  
 this.editor.updateOptions(monacoUpdateOptions);
