Gutenberg: Image Block: Changing alignment removes image resizing

[annezazu]

Describe the bug

After resizing an image and then setting the image size, if one chooses to change alignment on the image, the resizing is undone.

To reproduce
Steps to reproduce the behavior:

1. Create a new post
2. Add an image block
3. Manually resize the image using the image controls
4. Try resizing the image using "Image size" options under the Block Settings
5. Set alignment in the block editor and see image return to full size

This seems to only happen the first time this alignment is given to an image. For example, after alignment is given to an image, I can change the alignment without impacting the image size.

Expected behavior

I expected the image to just be aligned properly without impacting the size of the image.

Seems to be related to #23234 where you can't use image size controls in the new version of the editor.
