Description

In WordPress 6.3, if you set the image block to wide or full width, the image will not spread properly in the editor.

This problem occurs even with the latest Gutenberg plugin enabled. Also, it seems to occur when the original size of the image is smaller than the content width; I checked the difference with WordPress 6.2, and it may be due to the width:inherit being applied in this line.

Step-by-step reproduction instructions

• Add an image block
• Apply Wide Width or Full Width
