BUG: page.getMainComponent().view gives undefined when page is selected

Hi @iabhiyaan, when page:select triggers, iframes inside the canvas are not yet loaded, so you just need to wait once they are loaded before accessing its DOM.

editor.on('page:select', page => {
  const frame = page.getMainFrame();
  frame.once('loaded', () => {
    const rootEl = frame.getComponent().getEl();
    console.log(rootEl.querySelector('section'));  
  });
});

Thankyou @artf.
