The documentation https://wordpress.org/gutenberg/handbook doesn't contain information on how to style alignfull and alignwide.

• jQuery('body').width() returns 1884
• window.innerWidth returns 1901

When I do:

.alignfull {
	margin-left: calc( -100vw / 2 + 100% / 2 );
	margin-right: calc( -100vw / 2 + 100% / 2 );
	max-width: 100vw;
}

then the resulting container is 1901px wide (thus producing horizontal scrollbar). To make it right it would have to be 1884px.

Can you please clarify how themes should style alignfull?
