Large image is not resized within the editor (preview mode)

[DerekFangming]

Hi, there. When I'm trying to put in a large image (pixel size) into the editor, it squeeze down the textarea until it's completely gone. Take this image for example https://i.imgur.com/22PMF8I.jpg

Note that the horizontal scroll bar is already in left most position. Is there a way to instead scale the image to fit the preview window size (width, and keep the ratio ofc)?

Thanks!
