Column macro does not allow users to resize images on new editor

The Issue

On the previous editor, it was possible to edit the image's sizes when inserting a column macro. On the new editor though, you are only allowed to delete the image.

Steps to replicate

1. Create a new page
2. Insert a column macro
3. Insert an image
4. Try to resize it

Expected Results

You should be able to drag & resize images, just like you do with them on the page's body

Actual Results

You're not.
