Please what if I have an html file, How do you make sure that this is rendered at the appropriate position. A situation whereby I have a whole web page to be placed inside the editor, within the webpage there are custom designed images. My challenge is how to place the customBlot in the proper position while other tags used the embedded quill blot. Is it something that is possible to achieve?

For instance, I want to get the thumbnail of a video inside the video tag. I want the thumbnail to be render in the position of the video tag; whenever I place the html inside the editor.
