I'm trying to add images to a post with the following work flow using the Gutenberg editor on version 5.1.
Add an image block -> select upload -> select image.
The image is uploaded to the page and the media library but is cropped.
If I follow a DIFFERENT workflow: Add image block -> Media Library -> Upload Files -> Select files -> Select images
The image is uploaded and added, but only scaled down in size, which is what I want.
I've tried unchecking "Crop thumbnail to exact dimensions (normally thumbnails are proportional)" in media settings, and deactivating Smush, but no difference.
Changing the Image Size from Full Size, Large, Medium or Thumbnail makes no difference either as the copy of the image saved to the Media Library is itself cropped.
Can anyone help me so any images uploaded are not cropped? In the classic editor there was no problem.
I'm asking on behalf of someone not technical so I want to fix it so either upload method works fine.
Edit for Tom J Nowell's comments:
Here's a screenshot of the media library showing the cropped image (on the left), when I do "Add an image block -> select upload -> select image"
The image on the right has been uploaded from the WP Admin menu media library and is fine when added to posts.
Changing from Full Size to Medium, does make the cropped image appear weirdly narrower like this, but doesn't fix it, which makes me think it is the upload process causing it:
