Zoom Out: Canvas size incorrect in Post Editor

[scruffian]

What problem does this address?

On very large screens the canvas size in Zoom Out is larger than full width blocks:

What is your proposed solution?

Full width blocks should always go to the edge of the canvas:

Hey @scruffian,
I was replicating this issue, however I'm able to see Full width blocks reaching to edge of the canvas as expected
Using WordPress v6.7 and Gutenberg v18.8.0
Sharing the screenshot for better understanding:

I still see it, but only in the Post Editor:

I can no longer replicate the issue, including in the post editor.
