[Question]: Doctype in the canvas iframe

Question

Hi. This question has already been asked twice (here and here) but has never got an answer.

Is there a way to add <!DOCTYPE html> as the beginning of the canvas iframe so that the iframe will be in standards mode.

I need this since I am trying to use tinyMce as the custom RTE, and tinyMce requires standards mode.

In the next release, I'll add a new event helper that will allow editing iframe content before load:

editor.on('frame:load:before', ({ el }) => {
  const doc = el.contentDocument;
  doc.open();
  doc.write("<!DOCTYPE html>");
  doc.close();
});

Not really, but I'm open to solutions on how to make it customizable.
