Force image in "Image with text" layout to keep proportion and not get cut?

I’m having issues with the image in my “About” page. I’m using “Dawn” theme and the “Image with Text” layout. The image on the left used to keep the 1:1 ratio until I added more text on the right. Is there any custom code that could force the image to not get cut? (notice the arrows and the writing in the actual image on the left & the way it shows up in the screenshot on the right.) Thank you so much! :folded_hands:
